Threesome gone wrong led Spokane man to kill his girlfriend’s husband, court documents say

UPDATED: Fri., Aug. 14, 2020

A Spokane murder suspect told police he stabbed his girlfriend’s husband to death in a fit of rage during a sex party, court documents say.

Those documents say the killing occurred Wednesday night, in the Nevada Heights home shared by Edward Martinez, 19, his girlfriend, and Anthony Brines, 25. Brines and the woman were divorcing.

After a night of drinking, smoking marijuana and playing games, Martinez and the woman tried to have sex but failed, court records say.

Brines then began having sex with the woman in front of Martinez, according to court records.

The woman said she saw Martinez get a “weird look” on his face and begin laughing.

Martinez told police he “started feeling a deep anger inside of me just building, building.” He said he started “smiling and laughing at her ,” because this is what he does when he “gets sadistic.”

At this point, he had decided to stab Brines, the documents say.

Martinez left the room and returned with a knife and began stabbing Brines in the back, according to court documents.

After describing how he “finished the job” to police, Martinez began talking about hunting as a child, according to court documents.

Martinez told police he got “a rush” when he snapped an animal’s neck as a child. Police asked him if he got a rush from the stabbing, court documents say, and Martinez replied that “it was very short lived.”

After Martinez stabbed Brines, Davis said she called 911 and started screaming for help.

Police found Brines with stab wounds on his face, back and chest.

Two officers attempted lifesaving measures until paramedics arrived. The victim was pronounced dead at 6:35 a.m. Thursday.

Officers found Martinez in an alley and detained him on suspicion of first-degree murder.

He is being held on a $1 million bond in Spokane County Jail.
