The Catfish Killer: How a Snapchat Romance Led to Murder
You know that feeling when you hear a story that makes you want to immediately check your teenager's phone? This is one of those episodes. We're talking about nineteen-year-old Denali Brehmer, who fell for a guy on Snapchat who promised her nine million dollars to kill her best friend. And before you roll your eyes and think "teenagers are so gullible," let me tell you about the web of trauma, desperation, and manipulation that led to this tragedy.
This case has everything that makes our modern world terrifying. A fake online boyfriend, a murder-for-hire plot, and a group of teenagers who thought they could get away with the perfect crime. But at the center of it all is CeeCee Hoffman, a nineteen-year-old with autism who was working hard to build an independent life, and whose biggest mistake was trusting the wrong friend.
What happens when social media becomes a hunting ground? When someone's entire sense of reality gets warped by an online relationship? And how do you recruit four other teenagers to help you kill your best friend? We're diving deep into the psychology, the manipulation, and the heartbreaking chain of events that led to CeeCee's death on the banks of an Alaska river.
This isn't about judging teenagers for being naive. It's about understanding how desperation, trauma, and the false promises of strangers can turn ordinary people into killers. And it's about remembering that behind every viral true crime story is a real person who deserved so much better.

00:00:00,000 --> 00:00:05,500
You know that feeling when you hear a story that makes you want to immediately check your teenager's phone?
2
00:00:05,500 --> 00:00:07,800
This is one of those episodes.
3
00:00:07,800 --> 00:00:12,700
We're talking about 19-year-old Denali Bremer, who fell for a guy on Snapchat,
4
00:00:12,700 --> 00:00:16,500
promising her $9 million to kill her best friend.
5
00:00:16,500 --> 00:00:19,500
What happens when social media becomes a hunting ground
6
00:00:19,500 --> 00:00:24,500
and someone's entire sense of reality gets warped by an online relationship?
7
00:00:24,500 --> 00:00:28,000
This case has everything that makes our modern world terrifying.
8
00:00:28,000 --> 00:00:34,000
And at the center of it all, is C.C. Hoffman, whose biggest mistake was trusting the wrong friend.
9
00:00:55,000 --> 00:00:59,500
You know how people always say "Don't believe everything you see on the internet"?
10
00:00:59,500 --> 00:01:03,900
Well, 19-year-old Denali Bremer probably should have listened to that advice.
11
00:01:03,900 --> 00:01:09,900
Because the handsome millionaire she fell for on Snapchat turned out to be neither handsome nor a millionaire.
12
00:01:09,900 --> 00:01:14,200
And by the time she figured it out, her best friend was dead.
13
00:01:14,200 --> 00:01:18,300
This is one of those stories that makes you wonder how we got here as a society.
14
00:01:18,300 --> 00:01:25,800
Like, at what point did we decide anonymous strangers online were more trustworthy than the people actually sitting next to us?
15
00:01:25,800 --> 00:01:28,700
But, I'm getting ahead of myself.
16
00:01:28,700 --> 00:01:34,400
Denali Dakota Sky Bremer was born in 2001 in Anchorage, Alaska.
17
00:01:34,400 --> 00:01:37,200
Right off the bat, her life was complicated.
18
00:01:37,200 --> 00:01:43,000
She was the third of five daughters in a household that was basically a master-class and dysfunction.
19
00:01:43,000 --> 00:01:47,500
Her mother cycled through boyfriends like most people cycle through Netflix shows
20
00:01:47,500 --> 00:01:51,300
and none of these relationships were what you would call healthy.
21
00:01:51,300 --> 00:01:55,000
All the children were in and out of foster care throughout their young lives,
22
00:01:55,000 --> 00:01:57,300
which is already heartbreaking enough.
23
00:01:57,300 --> 00:02:01,000
But then something happened that would change everything permanently.
24
00:02:01,000 --> 00:02:06,700
One of her mother's boyfriends was charged with killing Denali's two-month-old baby sister.
25
00:02:06,700 --> 00:02:11,000
Think about that for a second, a baby, two months old.
26
00:02:11,000 --> 00:02:15,600
After that tragedy, all the surviving Bremer children were adopted into different families.
27
00:02:15,600 --> 00:02:20,100
The system was trying to give them better lives, and in many ways it worked.
28
00:02:20,100 --> 00:02:24,700
But some kinds of damage run deep, and they don't heal easily.
29
00:02:24,700 --> 00:02:31,700
Fast forward to 2019, Denali was 18 trying to figure her life out like most teenagers do.
30
00:02:31,700 --> 00:02:34,300
That's when she met Tyler on Snapchat.
31
00:02:34,300 --> 00:02:38,600
And Tyler seemed too good to be true, which should have been the first red flag.
32
00:02:38,600 --> 00:02:44,100
He was 21, supposedly gorgeous, and had won millions of dollars in the lottery.
33
00:02:44,100 --> 00:02:49,200
Because that's definitely how lottery winners spend their time trolling Snapchat for teenage girlfriends.
34
00:02:49,200 --> 00:02:52,300
But when you're young and you've been through what Denali had been through,
35
00:02:52,300 --> 00:02:55,300
sometimes you want to believe in fairy tales.
36
00:02:55,300 --> 00:03:00,700
Tyler lived in Kansas, so their entire relationship existed in the digital world.
37
00:03:00,700 --> 00:03:03,300
They'd spend hours messaging back and forth.
38
00:03:03,300 --> 00:03:07,300
And slowly, Tyler started revealing his true interests.
39
00:03:07,300 --> 00:03:08,700
He liked dominance.
40
00:03:08,700 --> 00:03:10,100
He liked control.
41
00:03:10,100 --> 00:03:13,500
And eventually, he admitted something much darker.
42
00:03:13,500 --> 00:03:16,700
Tyler wanted to watch someone die.
43
00:03:16,700 --> 00:03:20,700
Now, most people would have blocked him, and maybe reported him to the authorities,
44
00:03:20,700 --> 00:03:22,300
but Denali didn't run.
45
00:03:22,300 --> 00:03:26,900
Instead, she seemed intrigued by the idea of giving Tyler what he wanted,
46
00:03:26,900 --> 00:03:30,100
which brings us to the question that would change everything.
47
00:03:30,100 --> 00:03:36,100
If Tyler paid her $9 million, would she make a real snuff film for him?
48
00:03:36,100 --> 00:03:41,200
$9 million to someone who'd grown up in foster care, bouncing between homes.
49
00:03:41,200 --> 00:03:49,200
That kind of money represented everything she'd never had, security, freedom, and a completely different life.
50
00:03:49,200 --> 00:03:52,400
Enter Cynthia Hoffman, who went by C.C.
51
00:03:52,400 --> 00:03:57,600
She was 19, the same age as Denali, and they'd been best friends since high school.
52
00:03:57,600 --> 00:04:02,400
C.C. had been there for Denali through all her foster care transitions and family drama.
53
00:04:02,400 --> 00:04:08,400
She was exactly the kind of friend that everyone needs, loyal, supportive, and genuinely caring.
54
00:04:08,400 --> 00:04:14,000
C.C. had her own challenges. She was born with the learning disability and high functioning autism,
55
00:04:14,000 --> 00:04:18,800
which meant she needed extra support in school and took longer to learn new things.
56
00:04:18,800 --> 00:04:21,400
But she was determined to be independent.
57
00:04:21,400 --> 00:04:25,600
She worked at local restaurants and helped her father with his handyman business.
58
00:04:25,600 --> 00:04:29,400
She was building a life for herself, one small step at a time.
59
00:04:29,400 --> 00:04:34,800
But teenage friendships are complicated, and there'd been some drama over a boy named Zach.
60
00:04:34,800 --> 00:04:41,600
Denali felt betrayed by something C.C. had done, and when she told Tyler about it, he saw an opportunity.
61
00:04:41,600 --> 00:04:47,200
"If C.C.'s actions hurt you so much, why don't you get her back?"
62
00:04:47,200 --> 00:04:54,200
And that's when the plan crystallized. Denali would have her $9 million, and she'd have her revenge.
63
00:04:54,200 --> 00:04:57,200
Here's where the story gets even more disturbing.
64
00:04:57,200 --> 00:04:59,800
Denali didn't plan to do this alone.
65
00:04:59,800 --> 00:05:05,600
She recruited four other teenagers to help her, two of whom were under 15 years old.
66
00:05:05,600 --> 00:05:12,200
Let that sink in. Children barely old enough for high school were being pulled into a murder plot.
67
00:05:12,200 --> 00:05:19,600
The older accomplices were 16-year-old Caden Macintosh and Caleb Leland, who would drive them to and from the scene.
68
00:05:19,600 --> 00:05:25,000
Denali promised all of them a share of the $9 million Tyler was supposedly going to pay,
69
00:05:25,000 --> 00:05:34,400
because apparently nobody stopped to think about why some random guy in Texas would pay teenagers in Alaska $9 million for a murder video.
70
00:05:34,400 --> 00:05:41,600
On June 2nd, 2019, Denali asked C.C. if she wanted to go on a hike to Thunderbird Falls.
71
00:05:41,600 --> 00:05:45,600
And their friend group, Hike, was code for going somewhere to get high.
72
00:05:45,600 --> 00:05:50,400
So the invitation didn't seem suspicious. It was something that they'd done before.
73
00:05:50,400 --> 00:05:58,600
C.C. was shot and killed on the banks of the river near Thunderbird Falls, but the path to that moment was calculated and cruel.
74
00:05:58,600 --> 00:06:05,400
The group suggested they duct tape each other and take photographs, as part of what they presented as harmless fun.
75
00:06:05,400 --> 00:06:11,600
C.C. agreed to go first. She let them bind her wrists and feet with duct tape, then cover her mouth.
76
00:06:11,600 --> 00:06:17,000
It was only when she was completely helpless that she realized something was terribly wrong.
77
00:06:17,000 --> 00:06:24,200
While Denali and the others documented everything through Snapchat, sending pictures and videos to Tyler back in Kansas,
78
00:06:24,200 --> 00:06:29,000
Caden Macintosh took the gun from Denali and shot C.C. in the back of the head.
79
00:06:29,000 --> 00:06:32,600
Afterward, Hoffman's body was placed into the river.
80
00:06:32,600 --> 00:06:36,800
The group drove back to Anchorage thinking they were criminal masterminds.
81
00:06:36,800 --> 00:06:41,400
They burned C.C.'s clothes, her purse, her phone, and the murder weapon.
82
00:06:41,400 --> 00:06:46,600
Then they sent a message to C.C.'s sister, saying they dropped her off at a local park.
83
00:06:46,600 --> 00:06:51,600
But here's the thing about murder. It's not actually that easy to get away with.
84
00:06:51,600 --> 00:06:55,400
C.C.'s family realized she was missing almost immediately.
85
00:06:55,400 --> 00:07:00,000
The police tracked her movements to Thunderbird Falls and found her body the next day.
86
00:07:00,000 --> 00:07:04,200
Within hours, all five teenagers were arrested.
87
00:07:04,200 --> 00:07:07,000
So what about Tyler and his millions?
88
00:07:07,000 --> 00:07:13,400
When police tracked him down and brought him to Alaska, the truth was almost laughably pathetic.
89
00:07:13,400 --> 00:07:20,000
Tyler was actually Darren Schmiller, a shy, awkward young man from a small town in Indiana.
90
00:07:20,000 --> 00:07:25,000
He wasn't handsome, he wasn't rich, and he definitely wasn't a lottery winner.
91
00:07:25,000 --> 00:07:28,000
Darren was the kind of person who made others uncomfortable.
92
00:07:28,000 --> 00:07:33,400
He'd harassed classmates in school, asking them to send pictures of themselves in bikinis.
93
00:07:33,400 --> 00:07:38,000
When that didn't work, he'd approach their mothers and ask for photos of their children.
94
00:07:38,000 --> 00:07:43,800
His online relationships consistently fell apart when he started making similar requests.
95
00:07:43,800 --> 00:07:48,400
In Denali, he found someone who didn't run away from his darker impulses.
96
00:07:48,400 --> 00:07:53,600
And in him, she'd found someone that she thought could lift her out of the life she'd been born into.
97
00:07:53,600 --> 00:07:58,200
They were both chasing fantasies and C.C. Hoffman paid the price.
98
00:07:58,200 --> 00:08:05,800
Denali Brenner, now 24, pleaded guilty to murder in 2023 and was sentenced to 99 years in prison.
99
00:08:05,800 --> 00:08:10,600
The prosecution argued that she deserved the maximum sentence because she had engaged in, quote,
100
00:08:10,600 --> 00:08:13,600
"one of the most serious crimes that we have seen in Alaska"
101
00:08:13,600 --> 00:08:17,400
and had executed C.C. in a murder for higher plot.
102
00:08:17,400 --> 00:08:21,800
Darren Schmiller also received 99 years for his role in the conspiracy.
103
00:08:21,800 --> 00:08:28,800
Caleb Liehlund, who drove the group to and from the scene, pleaded guilty to second-degree murder and received 30 years.
104
00:08:28,800 --> 00:08:32,400
McIntosh's trial, in the case, is still pending.
105
00:08:32,400 --> 00:08:39,400
Two juveniles who were under 15 at the time have had their cases handled privately as is typical for minors.
106
00:08:39,400 --> 00:08:47,000
This case raises uncomfortable questions about how we live now, about social media, about online relationships,
107
00:08:47,000 --> 00:08:52,400
about the desperation that can drive people to believe in impossible promises.
108
00:08:52,400 --> 00:08:57,400
C.C. Hoffman was working to build an independent life despite her challenges.
109
00:08:57,400 --> 00:09:00,200
She was loyal to her friends and close to her family.
110
00:09:00,200 --> 00:09:06,200
She deserved to grow up, to achieve her goals, to experience all the ordinary joys of life.
111
00:09:06,200 --> 00:09:15,200
Instead, she became the victim of a plot that existed primarily in the digital world until it suddenly, violently, didn't.
112
00:09:15,200 --> 00:09:17,800
The tragedy is that none of this had to happen.
113
00:09:17,800 --> 00:09:22,200
If Denali had talked to literally any adult about Tyler's promises,
114
00:09:22,200 --> 00:09:27,600
if she'd stopped to think about why a millionaire would pay teenagers millions for murder videos,
115
00:09:27,600 --> 00:09:32,000
if she'd chosen to work through her feelings about C.C. like normal friends do,
116
00:09:32,000 --> 00:09:35,600
everyone involved might have had different lives.
117
00:09:35,600 --> 00:09:37,600
But that's not how this story ends.
118
00:09:37,600 --> 00:09:47,600
Instead, it ends with a young woman dead, several teenagers behind bars, and families destroyed by choices that started with a lie on social media.
119
00:09:47,600 --> 00:09:50,600
Sometimes the internet connects us to wonderful things.
120
00:09:50,600 --> 00:09:53,600
Sometimes it connects us to people who destroy lives.
121
00:09:53,600 --> 00:09:57,600
The difference is learning to tell which is which.
122
00:09:57,600 --> 00:10:07,600

127
00:10:29,600 --> 00:10:31,600
Anyplace that's possible.
128
00:10:31,600 --> 00:10:35,600
Let's get to a quick email from one of you that listens, subject, this one's weird. Sorry.
129
00:10:35,600 --> 00:10:36,600
Joe.
130
00:10:36,600 --> 00:10:43,600
Okay, this is more personal than true crime, but have you ever had a dream where you're the victim or the killer?
131
00:10:43,600 --> 00:10:49,600
I had one last night after falling asleep to your podcast, and I woke up genuinely stressed about where I hit the body.
132
00:10:49,600 --> 00:10:53,600
Anyway, love the show, you have the best, let me tell you a story voice.
133
00:10:53,600 --> 00:10:56,600
Hannah, recovering sleep walker.
134
00:10:56,600 --> 00:10:58,600
Hannah, that's disturbing.
135
00:10:58,600 --> 00:11:01,600
I love that you're falling asleep listening to the podcast, by the way, I get that a lot.
136
00:11:01,600 --> 00:11:07,600
If you haven't tried that, I understand I don't do this myself because it's weird to listen to myself as I fall asleep.
137
00:11:07,600 --> 00:11:08,600
I don't do that.
138
00:11:08,600 --> 00:11:13,600
But I hear it a whole bunch that people go to bed and listen to my podcast as I fall asleep.
139
00:11:13,600 --> 00:11:16,600
They just keep binging and binging episodes until they fall asleep.
140
00:11:16,600 --> 00:11:23,600
So I guess this is what Hannah's doing, but Hannah, I've never had a dream where I was the killer.
141
00:11:23,600 --> 00:11:25,600
I don't think, not that I remember.
142
00:11:25,600 --> 00:11:30,600
I've had a million of them where I've been the victim, where someone's chasing me or is after me.
143
00:11:30,600 --> 00:11:31,600
I call those nightmares.
144
00:11:31,600 --> 00:11:34,600
I have them often, as I've documented in the past on this show.
145
00:11:34,600 --> 00:11:35,600
But think God never the killer.
146
00:11:35,600 --> 00:11:37,600
I don't know what I would even do.
147
00:11:37,600 --> 00:11:38,600
I guess that's normal.
148
00:11:38,600 --> 00:11:43,600
I think you're normal, Hannah, but knock on wood, I've never done that myself.
149
00:11:43,600 --> 00:11:47,600
All right, thank you for the email and thank you for listening to 10 Minute Murder.
150
00:11:47,600 --> 00:11:48,600
I will see you in the next one.
151
00:11:48,600 --> 00:11:49,600
Later.
