Police Tuesday asked for help in hunting down a man who allegedly fled a Midway Drive gym parking lot after fatally shooting another man on Feb. 25.

The San Diego Police Department is searching for Ernesto Castellanos Martinez, who is accused of gunning down Alexander Mazin, 27, outside 24 Hour Fitness on that Sunday morning.

Mazin died at the scene from wounds to his upper body.

About an hour after the Feb. 25 shooting, officers surrounded a North Park residence where they thought Martinez might be located. Following a roughly six-hour standoff, a SWAT team forced entry to the apartment, but the suspect had escaped.

Police think Martinez and Mazin were acquainted.

Martinez, who also goes by Ernesto Castellanos, is described by police as a 41-year-old bald Hispanic man with brown eyes. He is 5 feet, 10 inches tall and weighs 185 pounds.

Anyone with information about Martinez is asked to call the San Diego Police Department’s Homicide Unit at (619) 531-2293 or the San Diego County Crime Stoppers anonymous tip line at (888) 580-8477.

Crime Stoppers is offering up to $1,000 for information that leads to an arrest in the case.
