A woman called and talked to the man accused of murdering her son in Vancouver prior to his arrest, according to court documents.

The body of 25-year-old Cody W. O’Brien was found on the Burnt Bridge Trail at Arnold Park on July 26.

William DeWayne Peek, 27, of Vancouver, was arrested Thursday on the charge of first-degree murder. He made his first court appearance Friday.

Court documents state O’Brien was reported as a missing, endangered and possibly suicidal person out of Gresham on July 18. In the report, it stated a firearm was believed to have been stolen by O’Brien.

His death was ruled a homicide and the medical examiner determined he had been shot multiple times.

O’Brien’s mother told investigators Peek was possibly the last person to be with her son, according to a probable cause affidavit.

Mother calls suspect

The affidavit states that when O’Brien stopped answering his phone, she went through his phone records and called a number with a 360-area code that was answered by Peek.

Peek told the woman he had “smoked a bowl” with O’Brien on the night of July 17 before an altercation over O’Brien wanting to rob a drug dealer for “white stuff,” according to the affidavit.

The woman told investigators her son smoked marijuana for back pain, but had otherwise been “clean” for a few years and would not have been looking for drugs like methamphetamine.

She also said he has a medical condition that would not make it reasonable for him to be involved in a physical fight, according to court documents.

Witness statements

One witness who knew both men told investigators Peek had been texting with O’Brien and planned on killing him and taking his car, according to a probable cause affidavit.

The affidavit states Peek left to meet O’Brien between 12:30 and 1 p.m. July 17 and returned an hour later with an injury to his left eye and right knuckle.

Court documents state Peek admitted to the witness he had punched O’Brien, pushed him to the ground and took an expandable baton from O’Brien during the fight.

Court records show July 17 was O’Brien’s birthday.

Another witness told investigators Peek wanted to get revenge on people for “jumping” him, according to court documents.

Peek said he was actively searching out those people and planned to get to one of them by pretending to sell fake drugs.

Peek told the witness that one of the people was now a missing person and he had viewed his body in a wooded area and he was “bleeding out” with “bullet holes” in his body, according to a probable cause affidavit.

The affidavit states Peek told the witness the missing man’s mother called him to ask about her missing son.

Victim's mother, suspect's brother react

Investigators said phone records showed Peek’s phone was in the area of a cell tower close to where O’Brien’s body was located.

A probable cause affidavit states the bullets recovered from O'Brien's body matched those from the gun reportedly stolen by O'Brien.

After his arrest, Peek told police he was with O’Brien in his car and that he and O’Brien had “words” due to O’Brien wanting to commit a robbery. The conversation ended when Peek asked for an attorney.

Peek’s brother, outside the courtroom Friday, said drugs had messed up his brother’s life.

“I’m tore up. I’m tore up inside, but at the same time, he made his bed, so he’s got to lie in it,” Joe Peek said. “I feel bad for the victim and the victim’s family.”

O'Brien's mother told FOX 12 her son had special needs and multiple medical problems. She said he was a "kind soul" who was too trusting of people and "just wanted true friends and be accepted the way he was and fit in."

"He had a good heart and enjoyed being a little goofy to make people laugh especially me, his mom," she said.

Peek has prior convictions for burglary and theft, according to court records, but no previous violent crimes.

He is due back in court Aug. 15 and his bail was set at $750,000.
