A man suspected of killing two people in Idaho is now the prime suspect in the shooting of a UA student on March 20, Ada County Sheriff’s Department officials announced Friday during a press conference in Boise, Idaho.

Jake Thompson, an engineering management senior, was shot three times outside his home, near East Grant Road and North First Avenue sometime that night.

The suspected is believed to be John Delling, 21, who went to Timberline High School with Thompson.

Thompson was in his house near the UA, when the suspect tapped on Thompson’s window and told Thompson to move his truck. While Thompson was moving his truck, the suspect rode past on a bicycle and fired five shots at the driver’s side door, hitting Thompson three times.

Thompson was struck in the head, shoulder and arm, said Ada County Sheriff Gary Raney. He was taken to nearby hospital.

George Humphrey, University Medical Center spokesperson, confirmed Friday that a man named Jake Thompson was released from the hospital on March 24.

Delling was arrested Tuesday by police in Sparks, Nev., on a first-degree murder warrant issued by Moscow, Idaho police in the death of University of Idaho senior David Boss, also a former high school classmate of Delling’s.

Boss, a 21-year-old UI history senior, was killed Saturday at his apartment after allegedly being shot twice in the head by Delling.

Authorities have also linked Delling to the death of Bradley Morse, 25, whose body was found Tuesday by an Idaho Parks and Recreation employee in a pond on Parks and Recreation Property. Morse worked as a janitor for Idaho Parks and Recreation and was also a computer science senior at Boise State University.

Delling drove 6,500 miles across much of the West, including California, Idaho, Oregon, Washington, Utah, Arizona and Nevada, during a four-week period prior to the killings in Idaho, Raney said.

Family and friend’s of Delling said he was acting increasingly erratic before the slayings.

Thompson has identified Delling as his assailant but doesn’t know why he was targeted, Raney said.

Thompson could not be reached for comment.

Idaho authorities expect to prosecute Delling for the slayings before he would go to Arizona to face possible charges there.
