A San Francisco man arrested in connection with a fatal shooting at a weekend gay pride event is no longer considered a suspect in the death.

Authorities say the .357 revolver found on 20-year-old Ed Perkins was not the weapon used to kill 19-year-old Stephen Powell in San Francisco's Castro district late Saturday. Witnesses did not place Perkins at the scene of the shooting.

Perkins initially was arrested on suspicion of murder, but is now only facing charges of possessing a concealed weapon and possessing a loaded weapon. He's scheduled for arraignment Wednesday morning.

Police have said they believe Powell knew his shooter. They say two innocent bystanders suffered gunshot wounds to the leg in Saturday's attack.
