A SERIAL killer has boasted of outsmarting prosecutors in a horrifying 13-page letter to a journalist.

Keith Hunter Jesperson – aka the Happy Face Killer – also confessed to the exact location he took the life of one of his eight victims.

Jesperson is a Canadian-born serial killer who confessed to brutally murdering his victims in multiple different U.S. states while working as a truck driver.

He was arrested in 1995 on suspicion of killing a woman in Washington state.

He was dubbed the Happy Face Killer because he drew smiley faces on letters he sent to the media and cops, prosecutors said.

Jesperson eventually confessed to killing eight women between 1990 and 1995 in California, Washington, Oregon, Florida, Nebraska, and Wyoming.

He currently is serving four life sentences without possibility of parole in Oregon.

His seventh victim, Angela Subrize, met her tragic fate at the age of 22 during a week-long road trip with him from Washington to Indiana.

According to Jesperson, Subrize became impatient with how long the journey was taking and asked him to speed up as she wanted to see her boyfriend.

Jesperson responded by raping and strangling her. He then strapped her body to the underside of his truck and started driving, dragging her, he’d later tell the cops.

NEW LETTER

He has now written further information about the death of Subrize.

In his lengthy fourth letter to Ashleigh Banfield, a journalist at NewsNation, he went into graphic detail about the young woman’s murder.

The monster wanted to correct the record about her gruesome killing, which he carried out in 1995.

“Ashleigh, I didn’t kill Angela Subrize in Wyoming.

“I killed her at the rest area at mile marker 58/59 on interstate 80 in Nebraska.

“I was in Wyoming because of Ken Lee Monsebroten, a jail house rat-informer,” he wrote.

His customary smiley face drawings were etched into the letter.

Jesperson, 69, also gloated about tricking the district attorney’s office.

“They wanted a deal and [to] send me home. We played the game for months,” he wrote.

OUTSMARTED

His letter outlined, too, how he outwitted prosecutors or even lied to amuse himself.

“The Seattle weekly news magazine did a story in a January 1998 issue called The Confessions of the Happy Face Killer.

“The last paragraph summed it all up. Because I am a convicted killer, anything I tell people can be taken as something it isn’t,” he wrote.

DEPRAVED

His daughter, Melissa Moore, has previously spoken about his double-life.

Moore was just a teenager when her father was arrested.

The shocking reality of his depraved life and the realization of his heinous crimes pulled the rug from under her family and left them in a state of emotional free-fall for several years, she said.

Now in her early 40s, Moore has spent the past two decades working with family members of serial killers.

She helps them to rebuild their lives, and cope with the media intrusion and emotional minefield.

“There is no playbook for what you should do after hearing your husband or father is an alleged serial killer. It’s truly one moment at a time, to eventually one day at a time,” Moore explained.

APOLOGY

Last October she issued an emotional apology to the family of one of his victims after she had finally been identified after almost three decades.

In 1996, a year after his arrest in connection with seven homicides, Jesperson told cops he’d also murdered an unknown woman by the name of “Susan” or “Suzette” along Interstate 10 in Holt, Florida, in August 1994.

Her remains were found a month after her murder by an inmate worker crew, but her identity remained a mystery for 29 years.

Then, in a major breakthrough, Okaloosa County Sheriff’s Office (OCSO) announced she had finally been identified as Suzanne Kjellenberg.

Kjellenberg was 34 years old at the time of her murder, and had been hitchhiking across the country.

Moore told The U.S. Sun that she had been deeply saddened by the confirmation of Kjellenberg’s death and issued her apologies to the tragic woman’s family.

“I’m deeply saddened to know my father is responsible for the suffering and the murder of Suzanne L. Kjellenberg,” she wrote in a statement.

“I’m grateful for the dedication of local authorities in pursuing her identity for nearly three decades.

“While I know this will not bring closure for her loved ones, I’m grateful that it provides answers.

“Suzanne deserved a beautiful long life and I’m sorry it was cut horrifically short by my father.

“Sending my prayers and support to her family and friends.”
