SPOKANE VALLEY -- A 33-year-old pregnant woman is dead and her 19-year-old boyfriend has been arrested in connection with an overnight homicide in the Spokane Valley.

Spokane Valley Police booked 19-year-old Robbie W. Bishop into the Spokane County Jail at around 2:00am Sunday morning on charges of Second-Degree Murder.

Bishop's relatives called 911 just before 8:00 p.m. on Saturday after he called them saying he'd killed his girlfriend.

Josie Jordan wasn't surprised when the police showed up in her neighborhood in the 900 block of N. Bowman a little while after the 911 call. 

"They blocked off the roads with the police tape and everything, guns were drawn," Jordan said. "There's a lot of drug trafficking going on and there's a lot of alcohol-substance abuse and violence. Cops are here every weekend."

Police attempted to contact whoever was inside by using the public address system on their patrol cars and by calling inside the home.

After getting no response, officers entered the house and found the 33-year-old pregnant woman dead on the living room floor. Police believe she was five months pregnant.

Police followed a blood trail out of the back of the home which they believed to be the suspect's. Officers searched the neighboring home which belonged to the victim's sister but the search turned up nothing.

Officers began to investigate where Bishop had been at the time. It was then that Major Crimes detectives were called in to help police at the scene.

"I believe the resident there is [Bishop's] step-mom and he and the girlfriend needed a place for two or three weeks," said Spokane County Sheriff's Office Spokesperson Sgt. Dave Reagan.  

Just before 10:00 p.m., a man called authorities and reported that somebody was hiding in his boat about two blocks north of the crime scene where Bowman Road dead-ends near the freeway.

"I was sitting out in the middle of the street with my friends," said Michael Taylor. "We saw some guy run into our boat and hop over the fence."

When police showed up to the Taylor's home, Bishop jumped out of the boat and started running west. Officers caught him under a house in the 7300 block of E. Cataldo.

"I was standing way back here and I could seem them holding him down," Taylor said.

Bishop sustained minor injuries when officers tackled him, and he was taken to a local hospital to be checked out before heading to the public safety building for questioning.

"We actually found blood on the fence behind the victim's residence indicating that maybe he'd gone over the fence," said Reagan. "It sounds like he may have injured himself during the assault inside the trailer or in fleeing from the scene."

Spokane Valley Police say the victim's next of kin have been notified of her death, but they are not releasing her name until an autopsy can be performed.

For those that live in the neighborhood, the whole ordeal comes as a shock.

"The kids, they know about it and they're, they're pretty well scared," Jordan said.

Detectives with the Spokane County Sheriff's Office and sheriff's forensics specialists spent most of Saturday night and Sunday morning at the victim's house processing evidence.

Investigators did recover weapons at the scene, but they are not releasing anymore details about what was taken until a cause of death has been determined.
