San Francisco police have identified a suspect in a shooting Friday evening that killed one man and injured another near Golden Gate Park’s panhandle area.

Joel Armstrong, 31, a transient, allegedly killed a 28-year-old San Francisco man and left a 35-year-old San Francisco man with life-threatening injuries.

The dead man was identified as Milkon Isleyen, 28.

The shooting was reported at 6:28 p.m. Friday at Oak and Stanyan streets. Police said it appears Armstrong shot the two men during an argument among a group of people.

Armstrong allegedly ran to Fell Street, a block away, and used the gun to carjack a vehicle in which he then fled.

Saturday at 12:13 a.m., officers said they found the stolen vehicle on Alameda Street near De Haro Street, in the Design District. The vehicle was unoccupied, but it was parked behind a recreational vehicle that was occupied, police said.

Several people left the RV when officers asked them to, but one man — later identified as Armstrong — stayed inside, they said. During the attempt to make contact with Armstrong, one officer fired his weapon.

A tactical unit and a crisis/hostage negotiation team arrived at the scene, and around 2:20 a.m., Armstrong came out of the RV. He was taken into custody and transported to the hospital for an evaluation.

No injuries were reported in the officer-involved shooting, police said.

The incident is being investigated by the Police Department’s homicide detail, the San Francisco District Attorney’s Office, the Department of Police Accountability and the Police Department’s internal affairs unit.
