Detectives are asking for the public's help finding Pedro Gonzalez, 31, an Arlington man wanted in connection with the shooting death of Julio Rodriguez-Ochoa, 25, also of Arlington.
Rodriguez-Ochoa was shot early Sunday at the Cooper Park Apartments, 1001 Cooper Square Circle.

Gonzalez is 5-foot-7 and weighs 170 pounds. Police said he might be trying to get to Mexico.
Detectives are working with state and federal agencies to find him.
