Cynthia Lyn Rose
Later in 1992, another woman died.
Cynthia Lyn Rose.
Her body was found in California.
Jesperson later claimed responsibility.
By this stage his crimes were not generating one obvious multi-state alarm.
That is important.
Modern audiences know they are reading the chronology of one serial killer.
Investigators in 1992 did not.
Imagine each case without the name Keith Jesperson written above it.
A dead woman appears near one California city.
Another unidentified woman is found along a highway.
An Oregon woman is discovered months later.
Local police investigate each crime according to local evidence.
Unless physical evidence matches or detectives communicate across jurisdictions, the common offender remains invisible.
Serial murder exists as a pattern before police can necessarily see that pattern.
Laurie Ann Pentland
Laurie Ann Pentland was another Oregon victim.
Her body was discovered in November 1992.
Jesperson eventually admitted killing her.
The crime added another point to a map that still did not look like a map to investigators.
Portland.
California.
Oregon again.
The killer was traveling.
That meant traditional geographic profiling was less useful.
He did not return repeatedly to one neighborhood.
His workplace itself moved.
Highways connected his crimes.
Not streets.
The Smiley Face Returns
By 1994, Jesperson's need to communicate returned in a much more dangerous form.
This time he did not rely only on graffiti.
Anonymous handwritten letters appeared.
One reached Oregon's legal system.
Another went to The Oregonian.
The writer claimed responsibility for Taunja Bennett.
He also claimed other murders.
The letter to the newspaper went farther than the restroom graffiti.
It described multiple killings.
Some details were precise.
Some apparently had never been publicly released.
The writer described himself as a truck driver.
He talked about wanting to be noticed.
And on the page was the now-familiar little face.
The smile.
The letters created a new problem.
Pavlinac and Sosnovske had already been convicted.
The legal system considered Taunja's murder solved.
So who was writing?
A supporter of the prisoners?
A disturbed attention seeker?
A murderer?
Or a serial killer trying to tell the truth?
The Prosecutor Who Had Already Won
Jim McIntyre had helped prosecute the case against Pavlinac.
When the anonymous Happy Face letters appeared, his first instinct was skepticism.
That is understandable.
He had a jury verdict.
A recorded confession.
A defendant who had accurately pointed toward the body site.
Another defendant who had pleaded no contest.
The entire machinery of justice had already reached a conclusion.
Now an anonymous stranger was saying:
You got it wrong.
Accepting that possibility would require more than opening an investigation.
It would require questioning years of certainty.
McIntyre reviewed the letters.
Some details were wrong.
Others could have come from news articles.
But the second letter was harder to ignore.
The writer claimed multiple murders.
Some details appeared nonpublic.
The person said he was a long-haul truck driver.
Phil Stanford of The Oregonian began examining the claims closely.
The unknown writer became the Happy Face Killer in print.
Public pressure grew.
The district attorney's office could not simply ignore the possibility of a serial killer.
So investigators looked.
They explored suspects.
At one point attention focused on another man whose estranged wife thought his handwriting resembled the Happy Face letters.
Detectives traveled.
Interviewed people.
Built timelines.
It went nowhere.
By the summer of 1994, the letters once again looked like a dead end.
Pavlinac and Sosnovske remained behind bars.
Jesperson remained free.
The Problem With Anonymous Confessions
The Happy Face letters posed a classic investigative dilemma.
A confession can sound powerful.
An anonymous confession is much weaker.
Police need corroboration.
Does the writer know something genuinely secret?
Or has the writer studied news reports?
Can handwriting be connected to a known person?
Are there fingerprints?
Saliva?
A return address?
Travel records?
Anything outside the letter itself?
In 1994, investigators lacked a suspect to compare against the physical evidence.
They could lift prints.
They could preserve the envelope.
They could analyze the writing.
But a fingerprint means little if the person it belongs to is not in a searchable record.
DNA evidence was emerging as a powerful forensic tool, but databases and techniques were still far less comprehensive than today.
So the letters sat in a strange category.
Potentially explosive.
Potentially meaningless.
The investigation needed a person.
In 1995, a body in Washington would provide one.
Julie Ann Winningham
March 1995.
Julie Ann Winningham was forty-one.
Unlike many of Jesperson's other victims, Julie was not simply a stranger briefly encountered on the road.
She had been dating him.
Her family and friends knew about the relationship.
That changed everything.
When Julie disappeared, investigators had a name attached to the man she had been seeing.
She had introduced him.
He was a truck driver.
Tall.
Large.
His name was Keith.
Her body was found near the Columbia River corridor in Washington.
Police looked at the people closest to her final days.
This time the killer was not anonymous.
Investigators learned that Keith Hunter Jesperson, a long-haul trucker, had been in a relationship with Julie.
They traced his employer.
They learned where his trucking route had taken him.
By March 22, detectives located him in Las Cruces, New Mexico.
They questioned him for hours.
Jesperson admitted having a relationship with Julie.
He denied killing her.
He said they had argued and separated.
Police were suspicious.
But suspicion is not arrest evidence.
They did not yet have enough.
So Jesperson was released.
The mistake would not last long.
The Phone Call
After being questioned, Jesperson knew detectives were closing around him.
