A 27-year-old Bremerton man pleaded guilty to first-degree murder in the stabbing death of his wife, Girlie Quintana Weight, in their Montgomery Avenue home, according to Kitsap County Deputy Prosecuting Attorney Kate Sigafoos.

Michael Charles Cully pleaded guilty to murdering Weight while she showered March 24.

Cully called 911 to report his wife was “not breathing or moving, possibly as the result of a stabbing or shooting,” according to court documents.

Bremerton police arrived to the home in the 600 block of Montgomery Avenue to find 26-year-old Weight dead and slumped over the side of the bathtub.

Cully and Weight met in 2001 and married in 2005, according to court documents. They have a 1-year-old daughter together.

Cully first denied knowing anything about Weight’s murder, but eventually confessed to the crime. He admitted to police that he used a large butcher knife to stab Weight “about seven times” in the upper body area while she showered. Cully said they had been arguing about their relationship and he suspected Weight was having an affair, according to court documents.

Cully admitted to cleaning some of the bathroom after the attack and changing his clothes. He also told police he made phone calls, attempting to establish an alibi. Cully added that the couple’s 1-year-old daughter was in the house at the time of the murder, according to court documents.

He led investigators to a trash container on Nollwood Drive where they found the butcher knife used to stab Weight to death, according to court documents.

Sigafoos said Cully could be sentenced to 250-333 months or about 20-28 years of incarceration for Weight’s murder.

“The state’s recommending 333 months,” Sigafoos said.

Cully is scheduled to be sentenced Sept. 16.
