The suspect Seattle Police say killed two Seattle men in a “premeditated” and “unprovoked” June 1st attack at 29th and King after a night out on Capitol Hill has been captured by authorities after a weeks-long manhunt.

Ali Muhammed Brown, charged with two counts of murder in the slaying of 27-year-old Ahmed Said and 23-year-old Dwone Anderson-Young, was arrested Friday in New Jersey: 

Essex County, New Jersey Prosecutor’s Homicide Task Force and West Orange, New Jersey police arrested Seattle double-murder suspect Ali Muhammed Brown on warrant charges earlier this afternoon. Brown was arrested without incident and the investigation is ongoing. Seattle Police and King County Prosecutor’s Office representatives will be monitoring this case very closely.

“I want to thank the Seattle Police Department, the West Orange Police Department and the Essex County Prosecutor’s Office for their diligent efforts to bring Mr. Brown into custody,” Mayor Ed Murray said in a statement released by SPD. “All of our communities are safer today as a result. I hope his arrest brings some initial measure of closure to the families of Dwone Anderson-Young and Ahmed Said.”

“Seattle Police Homicide detectives have been working on this case relentlessly since day one. I personally offer my thanks to them and every other local, state and federal law enforcement official involved in the search for Mr. Brown and his eventual capture,” said Chief Kathleen O’Toole in the same statement.

Police say Brown shot the two men to death at 29th and King after a night out on Capitol Hill.

Details from court documents have described an attack possibly involving a hookup sex app. A friend of the two murdered men who saw them at R Place earlier in the night told police Said spent much of the evening on his phone and that he believed Said was using an app “like Grindr or Jack’d” — “These are phone apps on which gay men meet up with other gay men,” the police report noted. This friend told police he also saw the stranger with Said and Anderson-Young that night as they left R Place. That friend later identified the suspect Brown out of a police photo montage. Detectives were also able to retrieve video surveillance from a nearby business showing the suspect and Said and Anderson-Young together. Police say shell casings at the murder scene matched a 9 MM Smith and Wesson semiautomatic pistol purchased by the mother of Brown’s children that she said had gone missing. Police found Brown’s fingerprints and three spent 9mm shell casings inside Said’s car
