Investigators are seeking 18-year-old Michael Elijah Pulliambanks, aka Michael Banks, for the Dec. 20 shooting of 24-year-old Arnold Muckleroy.
Muckleroy was shot at about 5:15 p.m. on Rockspring Way in Antioch, according to police. He died at the hospital the next morning.
Police said Muckleroy drove to Rockspring Way to meet with some people, got in their car, and was shot in the head and dumped in the road.
The suspect vehicle, described as a dirty 1990s dark green two-door Ford Escort, has been recovered, police said today.
Police said a $500,000 arrest warrant had been issued for Pulliambanks for attempted murder. However, detectives will now be seeking a warrant for murder.
Pulliambanks frequents the Bay Area and Sacramento area, and is considered armed and dangerous, police said.
Anyone who sees him should call a local police department or Antioch police at (925) 778-2441.
