Kitsap County Sheriff's deputies are investigating a double homicide in Bremerton. The suspect remains at large.

Officials say a 29-year-old woman and 2-year-old boy were fatally shot early Saturday. A third victim, a man whose age is unknown, was airlifted to Harborview Medical Center in Seattle with life-threatening injuries.

The Kitsap Sun reports (http://bit.ly/1BFXjUs ) that the boy's mother was trying to shield him when he was shot, but the mother was not hurt. The woman who was killed was a roommate. Their names were not released.

Officials say they received reports of gunshots heard at the Kariotis Mobile Home Park just after 2 a.m. Saturday. When they arrived, they found the woman dead and the 2-year-old critically injured. The toddler was taken to Harrison Medical Center in Bremerton, but he later died.

Sheriff's Lt. Detective Earl Smith told the newspaper that the mother and boy had moved into the home three weeks ago. The boy's father lives outside Kitsap County, Smith said. The third victim was a neighbor who was visiting and was shot as he ran back to his residence, Smith said.

The man was shot in the lower abdomen and underwent surgery, Smith said. Detectives were waiting to interview the man, Smith said.

Investigators used a police dog to search the mobile home park, but the dog did not pick up the suspect's scent. "We feel confident the suspect is no longer in the mobile home park," Smith said.

Two other homes were hit with bullets, but no one was hurt, he said.

The Bremerton Police Department and Washington State Patrol have joined the Sheriff's Office in the investigation.
