EVERETT — A judge Monday ordered a Snohomish County man held on $1 million bail in connection with a Jan. 2 shooting that left an Everett man dead.

Detectives arrested Joshua Monson, 27, Friday in the Arlington area. A judge Monday found probable cause to hold Monson for investigation of sec

ond-degree murder.

Since the shooting, detectives have spoken to people who reported that Monson shot Brian Jones inside an apartment in the 12100 block of Meridian Avenue in Everett, according to court documents.

Detectives found Jones, 30, with a gunshot wound to the head. Investigators believe Jones was shot from behind while he was seated at a table, talking on a cell phone.

Four other people were believed to be in the apartment at the time of the shooting. They told investigators that they’d been using meth and marijuana in the hours leading up to the gunfire. None of them reported having witnessed the shooting, court papers said.

Detectives initially arrested Edward J. Lamourie, 40, who lives at the apartment with his girlfriend. Investigators found the suspected murder weapon hidden under his mattress, according to a police affidavit.

A judge held there was insufficient cause to jail Lamourie for investigation of murder. She did find there was sufficient grounds to detain him for a weapons violation. He admitted that he had a sawed-off shotgun in his apartment.

Lamourie remains behind bars on $1 million bail. He has not been charged with murder.

Deputies questioned Monson on the day of the shooting. He was spotted outside the apartment complex, waving his hands. He had a severe dog bite to his leg and had blood on his hands. He told the deputy: “Someone has been shot. You need to get an aid car,” court papers said.

He allegedly told detectives that he’d been in the bedroom with Lamourie getting high on methamphetamine when Jones was shot. He later changed his story, telling detectives he’d actually been in the bathroom. He said Lamourie’s pit bull attacked him during the commotion after the gunfire.

Detectives learned that Monson and Jones had dated the same woman. Witnesses told police that they’d seen Monson with a black handgun in the days leading up to the shooting and he’d made comments about wanting to kill someone who’d stolen from him, according to the police affidavit.

Other witnesses told investigators that Monson admitted to shooting someone in the back of the head, court papers said.

Monson has several felony convictions, including threatening a man with pipe bombs in 2006. He has a pending drug case stemming from an arrest on the day he was released from prison for a previous conviction.
