Summary of Beaver Lake homicide investigation


(King County) Summary of Beaver Lake homicide case and related officer involved shooting. (Case#C17004307/ C17004827)


On Wednesday January 25th just after 2:30 p.m. a 22 year old Sammamish man interrupted a car prowl to his vehicle while parked at Beaver Lake Park in Sammamish.  The man was run over and killed by the suspects as they fled the scene of the crime.

Detectives learned a credit card stolen from another vehicle in the same parking lot was used about an hour later at a Fred Meyer store in Renton.

Detectives obtained surveillance photos of two suspects attempting to use the stolen credit card.  An associate of the pair identified them as 17 year old female from Federal Way and a 16 year old male from Des Moines.

On Friday, January 27th, King County Sheriff’s detectives were conducting an undercover operation in the area of the 21600 block of 29th Ave. S in the city of Des Moines as part of the Beaver Lake Park homicide investigation.

About 10:30 p.m. detectives used a ruse to get a 16 year old male, who detectives believed was connected to the homicide, to come outside so he could be safely questioned.   However Detectives were approached by the 16 year old male and a 17 year old male, both armed with pistols.  Detectives identified themselves as law enforcement officers and ordered the pair to drop their weapons.  The 17 year old male fired his pistol at the detectives.  Three detectives returned fire, striking the male.   The other male, who was the one being sought by detectives, fled on foot.

The 17 year old male who had been shot was transported to Harborview Medical Center for treatment, but later died from his injuries. His pistol was recovered next to where he was found. The other male dropped his loaded pistol while fleeing. The pistol was later found where he dropped it.   He was eventually located hiding in a nearby apartment.  He was booked into Youth Services Center for weapons charges.  Detectives do not believe he was at the scene of the Beaver Lake Park homicide.

Detectives continued to search for the 17 old female who was seen in the surveillance photos from the Fred Meyer using a stolen credit card.   She was located Saturday morning at a house in the 6800 block of S 133rd St in Skyway as well as a 23 year old female who has been identified as the driver of the vehicle that killed the 22 year old man in Sammamish.

The 23 year old female was arrested and booked for Vehicular Homicide and the 17 year old female was arrested for Identity Theft and Possession of Stolen Property.  Both women were at the scene of the Beaver Lake Park homicide.

The three male deputies involved in the shooting are a sergeant, 42 years old who has 11 years with Sheriff’s Office; a detective, 36 years old and 10 years with Sheriff’s Office; and a detective, 36 years old with 5 years at Sheriff’s Office.
