EVERETT — John Blaine Reed spent three months on the run before police in Mexico caught up with him and promptly turned the fugitive over to U.S. authorities. On Friday, Snohomish County sheriff’s detectives booked the former Oso man into jail in Everett.

Reed, 53, had been housed in an Arizona jail since his arrest last month. He didn’t fight his return to Snohomish County, where he faces two counts of aggravated murder for the execution-style killings of his former neighbors, Patrick Shunn and Monique Patenaude.

Reed is expected in court Monday to answer the charges. He is represented by Snohomish County public defender Jon Scott.

It’ll be up to Prosecuting Attorney Mark Roe to decide if his office will seek the death penalty for Reed. Roe will have a month from the date of the arraignment to make a decision, unless the defense requests more time to provide materials in an effort to persuade the prosecutor not to seek Reed’s execution.

The only other punishment for an aggravated murder conviction is life behind bars without the possibility of release.

Snohomish County deputy prosecutor Craig Matheson has filed criminal charges against most of Reed’s immediate family. Reed’s parents, Clyde and Faye, were in court Thursday to answer to allegations they helped their son flee the country and discarded possible evidence. Faye Reed, 77, pleaded not guilty to the charge. Her husband, 81, asked for more time to hire an attorney.

Their other son, Tony Clyde Reed, admitted that he helped his brother bury the victims and dispose of their vehicles. Tony Reed pleaded guilty to rendering criminal assistance at a hearing last month.

He fled to Mexico with his brother, but surrendered in May. He later provided homicide detectives with information that led them to the grave where Shunn and Patenaude had been buried.

The couple’s bodies had been left in a clearcut area several miles from where detectives found their vehicles down an embankment.

The pair had been shot at close range. Patenaude, 46, likely was killed first on April 11, shortly after running some errands in Arlington. She was shot three times. Her husband, 45, likely was ambushed after returning home from work later that day, according to court papers. The former Army Ranger was shot once in the back of the head.

Records show that there was bad blood between Reed and his former neighbors for years. The only access to Reed’s former house was a driveway on his neighbors’ property. Reed and the couple had disputes regarding the road, its maintenance and access, Matheson wrote.

The feud grew worse after the Oso mudslide. Reed allegedly became upset about how the county was responding to property owners affected by the slide. His neighbors called authorities when Reed was driving heavy equipment into the Stillaguamish River to move logs and debris. Reed told county officials he was worried about flooding. He ended up pleading guilty to a misdemeanor for illegal wood debris collection.

Reed eventually sold his land to Snohomish County as part of the buyout program. Patenaude reported that Reed was squatting at this former home. County officials ordered him to collect his belongings and leave.

The day his neighbors disappeared, Reed told witnesses he was headed to his former home to collect the rest of his things.
