An 18-year-old man was arrested in Federal Way on Sunday night and is believed to be connected to the double homicide last month in Rainier Beach, police said.

Seattle police arrested the suspect June 7 with the assistance of U.S. Marshals and Valley SWAT team, according to a post on the Seattle Police Department blotter.

The suspect, Tayjuan Trevion Fletcher, was booked into King County Jail on multiple counts including investigation of homicide and unlawful possession of a firearm, according to jail records. His bail is set at $1 million.

Around 6:20 p.m. May 23, a large group of people were in the Rainier Beach Safeway store parking lot in the 9200 block of Rainier Avenue South, a previous post said.

When a disturbance broke out, witnesses reported shots being fired. The group fled in different directions, but two victims were left behind. Seattle police and Seattle Fire Department medics both responded to the parking lot.

The two victims were transported to Harborview Medical Center, but despite the attempted life-saving measures by the medics, both victims were declared deceased prior to arriving, the post said.

The male victims were identified by the King County Medical Examiner’s Office as Christopher Wilson Jr., 35, who died from a gunshot wound to the torso, and Christopher Roberts Jr., 23, who died from multiple gunshot wounds. The office ruled both deaths as homicides.
