TRACY, Calif. (KTXL) — After arresting one suspect, Tracy police say they are searching for a second suspect in a homicide that occurred in September.
On Sept. 21, police say 21-year-old Enrique Guillen-Valles and 28-year-old Nicole Diaz were involved in the killing of Nikolis Martinez.
Investigators believe the suspects knew Martinez and the homicide was not random.
Diaz was arrested but Guillen-Valles is still at large, according to police.
Police say Guillen-Valles possibly fled the area and should be considered armed and dangerous.
