Route 40 Killer: Steven Brian Pennell and the Blue Van of Death

There's something deeply unsettling about a killer who looks like everyone else. Steven Brian Pennell was a married electrician with two kids, the guy who'd wave to you from his driveway while mowing the lawn. Between 1987 and 1988, he turned a stretch of highway in Delaware into his own personal nightmare factory. Route 40 became a place where women disappeared into a blue van and were found days later showing signs of torture that would make seasoned homicide detectives need a minute. This is the story of how a female undercover cop stared into the eyes of a predator, how cutting-edge forensic science caught up with evil, and how a killer demanded his own execution while quoting the Bible and refusing to reveal where he'd hidden his final victim's body.

00:00:00,000 --> 00:00:08,720
November 29, 1987. It's Thanksgiving weekend. Two teenagers looking for a little privacy pull

2
00:00:08,720 --> 00:00:14,960
off on Route 40 in Delaware and spot what they think is a mannequin in the road. The boyfriend

3
00:00:14,960 --> 00:00:20,840
drives closer and that's when they realize it's a woman's body, bound and brutalized.

4
00:00:20,840 --> 00:00:24,240
This is the beginning of Delaware's only serial killer case.

5
00:00:24,240 --> 00:00:48,560
[Music]

6
00:00:48,560 --> 00:00:55,520
In the late 1980s, the stretch through Bear and Glasgow was lined with budget motels,

7
00:00:55,520 --> 00:01:01,680
truck stops and 24 hour diners. During the day, it looked like any American highway. At night,

8
00:01:01,680 --> 00:01:06,720
near construction sites and industrial areas, it felt isolated, vulnerable.

9
00:01:06,720 --> 00:01:12,640
Sex workers and hitchhikers used Route 40 because traffic was constant. The highway had this

10
00:01:12,640 --> 00:01:18,240
quality where you're near Wilmington, near civilization, but when darkness fell, you may as well

11
00:01:18,240 --> 00:01:23,440
have been in the middle of nowhere. That combination made it perfect for Stephen Bryan Penel.

12
00:01:23,440 --> 00:01:31,040
Shirley Anna Ellis was 23 in November 1987. She'd worked as a prostitute but was turning her

13
00:01:31,040 --> 00:01:37,040
life around, enrolled in nursing school. During the AIDS epidemic, when most people were terrified

14
00:01:37,040 --> 00:01:41,920
and healthcare workers refused to go near AIDS patients, Shirley was visiting them,

15
00:01:41,920 --> 00:01:47,920
bringing them food, showing up when society had abandoned them. On November 29, three days after

16
00:01:47,920 --> 00:01:53,360
Thanksgiving, Shirley left her family home around 6 p.m. carrying a platter that she'd prepared for

17
00:01:53,360 --> 00:02:00,400
an AIDS patient at Wilmington Hospital. She needed to make the 14-mile trek. Public transit basically

18
00:02:00,400 --> 00:02:06,640
didn't exist, so Shirley walked to Route 40 to hitchhike. That evening, a couple drove to a

19
00:02:06,640 --> 00:02:11,760
construction site looking for privacy. The boyfriend spotted something in the road. He told his

20
00:02:11,760 --> 00:02:18,320
girlfriend, "Hey, that looks like a mannequin." They drove closer. It wasn't. Shirley was found

21
00:02:18,320 --> 00:02:24,240
partially nude, hands and feet bound with adhesive tape, a ligature wound around her neck,

22
00:02:24,240 --> 00:02:31,360
her head bludgeoned with a hammer, the crucial detail. No sexual assault. The person who did this

23
00:02:31,360 --> 00:02:40,720
got off on the torture itself. Seven months passed, then on June 28, 1988, Catherine DeMaro, 31,

24
00:02:40,720 --> 00:02:46,720
was seen walking Route 40 around 11.30 p.m. By morning, construction workers found her naked body.

25
00:02:46,720 --> 00:02:54,240
Same pattern. Beaton-bound tortured. No sexual assault. Hammer. Strangulation. The

26
00:02:54,240 --> 00:02:59,520
Catherine's body gave investigators something new. She was covered in thousands of blue carpet fibers.

27
00:02:59,520 --> 00:03:05,200
Forensics determined they came from the vehicle's interior. Catherine had been forced to lie on a

28
00:03:05,200 --> 00:03:11,280
carpeted surface for an extended time. Every time she struggled, more fibers transferred to her body.

29
00:03:11,280 --> 00:03:15,680
Police now knew they were looking for a vehicle with distinctive blue carpeting.

30
00:03:15,680 --> 00:03:21,440
The FBI profile said they were dealing with a sadist who didn't need sexual penetration.

31
00:03:21,440 --> 00:03:29,120
The torture itself was the gratification. August 22, 1988. Margaret Lynn Finner, 27,

32
00:03:29,120 --> 00:03:34,720
goes missing. Last scene getting into a blue van. Her body was found near the Chesapeake and

33
00:03:34,720 --> 00:03:40,400
Delaware Canal, but decomposition destroyed most evidence. Penel was never charged, though

34
00:03:40,400 --> 00:03:47,680
everyone believes she was his victim. September 18, Michelle Gordon, 22, was seen entering a blue

35
00:03:47,680 --> 00:03:53,280
Ford van. A witness who knew both Michelle and a local electrician named Stephen Bryan Penel

36
00:03:53,280 --> 00:03:59,200
watched her climb in. Michelle's body was found September 20 on the rocks along the canal.

37
00:03:59,840 --> 00:04:05,040
The autopsy revealed cocaine in her system. The medical examiner believed the drugs weakened her

38
00:04:05,040 --> 00:04:10,640
heart and when Penel started torturing her, that shock caused her heart to stop before he'd finished.

39
00:04:10,640 --> 00:04:14,720
Michelle's body was dumped differently, tossed onto the rocks.

40
00:04:14,720 --> 00:04:22,720
Three days later, September 23, 26-year-old Kathleen Mayer vanishes. An off-duty officer spotted a

41
00:04:22,720 --> 00:04:29,280
young woman hitchhiking around 9.30 pm. He watched a blue Ford van pull over. Something felt off.

42
00:04:29,760 --> 00:04:34,960
So instead of intervening, he wrote down a license plate number as she climbed inside.

43
00:04:34,960 --> 00:04:40,240
The plate came back to Stephen Bryan Penel. Kathleen Mayer's body has never been found.

44
00:04:40,240 --> 00:04:46,320
Delaware police formed a massive task force. Over 60 officers, they brought in the FBI's

45
00:04:46,320 --> 00:04:54,160
behavioral science unit. They made a gutsy decision. Sinden a decoy. Officer Renee Trachner volunteered.

46
00:04:54,160 --> 00:05:00,000
She dressed like the women working Route 40. Got wired for sound and walked the dark highway while

47
00:05:00,000 --> 00:05:06,560
backup teams shattered her. On September 14, Renee noticed a blue Ford van cruise passed her seven

48
00:05:06,560 --> 00:05:13,360
times in 20 minutes. She moved to a darker stretch. The van stopped. The driver motion for her to come

49
00:05:13,360 --> 00:05:19,920
get in. Renee approached but did not get inside. She talked to the driver, a nervous white male who

50
00:05:19,920 --> 00:05:26,000
barely made eye contact. She later described his eyes as blank and cold, like there was no life

51
00:05:26,000 --> 00:05:32,080
behind them. While backup ran the plates, Renee had to think fast. She needed to see the inside

52
00:05:32,080 --> 00:05:37,600
without actually getting inside. She pretended to be interested in the van. She got him to turn on

53
00:05:37,600 --> 00:05:43,760
the dome light. When that light came on, Renee's heart stopped. The entire interior was covered

54
00:05:43,760 --> 00:05:50,320
in a distinctive blue carpet. The same fibers found on one of the victims. Renee made an excuse

55
00:05:50,320 --> 00:05:56,080
about being tired, saying that she needed to sleep. Penel got suspicious and drove off, but Renee

56
00:05:56,080 --> 00:06:01,440
had pulled fibers from the carpeting. Her backup team had the license plates, the driver's information

57
00:06:01,440 --> 00:06:09,120
everything. Stephen Bryan Penel, 31 years old, electrician, married father of two, without a criminal

58
00:06:09,120 --> 00:06:15,360
record. Police watched Penel for weeks. Renee ended up sitting next to a meta-moody blues concert

59
00:06:15,360 --> 00:06:20,720
during surveillance. His young daughter approached Renee to ask for a donation to a school fundraiser.

60
00:06:20,720 --> 00:06:27,280
Police observed Penel continuing to cruise Route 40, still hunting, even as the community panicked

61
00:06:27,280 --> 00:06:35,120
and the net was closing. On November 29, 1988, exactly one year after Shelley Ellis's body was found,

62
00:06:35,120 --> 00:06:42,160
Penel was arrested. Police searched the van. It was a mobile torture chamber. Eight pairs of

63
00:06:42,160 --> 00:06:48,720
pliers, handcuffs, whips, knives, needles, flex cuffs, two rolls of duct tape matching the tape

64
00:06:48,720 --> 00:06:54,400
used on victims. The blue carpet shedding fibers everywhere. Blood and hair samples matching the

65
00:06:54,400 --> 00:07:01,760
victims. Penel's trial began September 1989. First time DNA profiling was used in a Delaware criminal

66
00:07:01,760 --> 00:07:08,000
case. The science was so new that the judge held extensive hearings to determine "admissibility."

67
00:07:08,000 --> 00:07:14,400
They used RFLP testing to match blood from Penel's van to victims. The probability of it being someone

68
00:07:14,400 --> 00:07:21,840
else was essentially zero. The fiber evidence was equally damning. Perfect match. The jury convicted

69
00:07:21,840 --> 00:07:27,120
Penel of murdering Shelley Ellis and Catherine Demaro. They hung on Michelle Gordon because of her

70
00:07:27,120 --> 00:07:32,800
cause of death was complicated by cocaine. Penel received two consecutive life sentences,

71
00:07:32,800 --> 00:07:38,880
but prosecutors were not done. New evidence linked Penel to Michelle Gordon and Kathleen Mayor.

72
00:07:38,880 --> 00:07:44,800
They indicted him again. Penel then fired his attorneys and did the thing that I would encourage

73
00:07:44,800 --> 00:07:51,440
all serial killers to do? Represent yourself. He entered a no contest plea to both murders and then

74
00:07:51,440 --> 00:07:59,920
he asked to be sentenced to death. He cited the Bible, Numbers 3530 and Genesis 96. He framed his

75
00:07:59,920 --> 00:08:05,440
execution as God's law and state law aligning. He claimed he wanted to spare his family years of

76
00:08:05,440 --> 00:08:12,720
appeals. On October 31, 1991, the court sentenced him to death. A psychiatric evaluation described

77
00:08:12,720 --> 00:08:20,000
Penel as pleasant, attractive, friendly, no psychosis, no depression, no paranoia. The weird word

78
00:08:20,000 --> 00:08:25,280
there obviously being attractive. Because one, no he's not and two, why are you measuring that?

79
00:08:25,280 --> 00:08:33,840
So on March 14, 1992, Stephen Bryan Penel became the first person executed in Delaware in 46 years.

80
00:08:33,840 --> 00:08:38,720
In the days before, reporters tried to get him to reveal where he'd hidden Kathleen Mayor's body.

81
00:08:38,720 --> 00:08:44,960
Her family was begging. Penel refused almost every interview. Finally, he agreed to one with his

82
00:08:44,960 --> 00:08:50,960
lawyer present. He revealed nothing. When the time came for his last meal, Penel refused it. He

83
00:08:50,960 --> 00:08:56,240
didn't apologize to the family. He didn't show any remorse. He talked about abortion. He said he was

84
00:08:56,240 --> 00:09:02,160
refusing his last meal because 33 million babies had been aborted. Babies who died for no reason.

85
00:09:02,160 --> 00:09:08,240
While he was dying for a deed, he deserved death for. He was glad Christ forgave him. He said,

86
00:09:08,240 --> 00:09:13,520
"Those babies never got a first meal, so he wouldn't take a last meal in their memory." A man who

87
00:09:13,520 --> 00:09:18,720
tortured women to death with pliers and whips refused to tell a family where their daughter's body was

88
00:09:18,720 --> 00:09:24,400
hidden. He used his final breath to lecture about abortion and position himself as spiritually

89
00:09:24,400 --> 00:09:30,480
redeemed. After the conviction, prosecutor Kathleen Jennings received flowers. The card read,

90
00:09:30,480 --> 00:09:36,400
"You made us feel human again, from the women of Route 40." The women working that strip, women,

91
00:09:36,400 --> 00:09:42,080
society often ignored, sent flowers thinking the prosecutor for treating them like they mattered.

92
00:09:42,080 --> 00:09:47,520
Because to Penel, they didn't matter. They were objects he could use to satisfy his compulsion.

93
00:09:47,520 --> 00:09:54,080
To this day, Kathleen Mayor's family doesn't have a body to bury. Penel took that location to his grave.

94
00:09:54,080 --> 00:10:00,320
The case forced Delaware to professionalize its homicide investigations. It established DNA

95
00:10:00,320 --> 00:10:05,920
precedent still used today. But more than anything, it's a reminder that evil doesn't look like what we

96
00:10:05,920 --> 00:10:12,000
expect. Evil can be the guy who waves from his driveway. Evil can be the electrician with a wife

97
00:10:12,000 --> 00:10:18,800
and kids. Stephen Bryan Penel drove a blue van down a busy highway for over a year, hunting women

98
00:10:18,800 --> 00:10:24,800
in plain sight. Route 40 is still there. People still drive it every day. But for the families of those

99
00:10:24,800 --> 00:10:39,440
five women, that highway will forever be marked by the man who turned it into his personal nightmare.

100
00:10:41,360 --> 00:10:45,600
Thanks for listening to 10 Minute Murder, Bingeable True Crime Stories.

101
00:10:45,600 --> 00:10:52,480
I'm Joe, I'm the host, and here's an email, subject something about my commute. Hey Joe,

102
00:10:52,480 --> 00:10:56,560
I started listening to your podcast during a rough stretch at work when my commute felt like the

103
00:10:56,560 --> 00:11:01,440
longest part of my day. Somewhere along the way, it became the part that I didn't mind as much. Your

104
00:11:01,440 --> 00:11:05,760
episodes gave my brain something steady to hold on to instead of just looping my own stress.

105
00:11:06,320 --> 00:11:12,400
That probably sounds small, but it helped. Nina and Redlands, California, Nina, that means a lot to me.

106
00:11:12,400 --> 00:11:17,920
I've been told pretty often that I am on repeat and a lot of people's commutes too and from work.

107
00:11:17,920 --> 00:11:22,240
Some people have measured their commutes by the number of episodes they're able to get in on their

108
00:11:22,240 --> 00:11:27,040
way to and from. So again, thanks for the email. Hey, if you're a new listener to this podcast,
