LAPD Officer Henry Solis, 27, "should be considered armed and dangerous,'' according to a Pomona police statement released Monday afternoon.
Solis is wanted in the fatal shooting of Salome Rodriguez Jr., 23, who was gunned down near Third and Main streets in Pomona around 3:30 a.m. Friday and died at a hospital.
On Sunday afternoon, police recovered Solis' Volkswagen Jetta near the intersection of Main Street and Monterey Avenue, about four blocks from the shooting scene.
Police this afternoon said Solis may currently be driving a brown or tan 1992 Ford pickup truck, license number 4J79703.
Until the warrant was issued Monday, Pomona police had identified Solis as a "person of interest'' in the homicide investigation.
Pomona police said the shooting happened on the street following a fistfight at a nearby bar.
Following the shooting, Solis failed to show for his shift as a probationary officer at the LAPD Devonshire Division.
Solis, who joined the LAPD last June, has worked at the Devonshire Division in the San Fernando Valley since November and has had an unremarkable history in the department, LAPD Cmdr. Andrew Smith said.
Solis, whose last known address was in Pomona, is described as Hispanic, 5 feet 9 inches tall and weighing 185 pounds.
Police urged anyone with information about the killing or Solis' whereabouts to call the Pomona police detective bureau at (909) 620-2085, or Crime Stoppers at (800) 222-8477.
