Authorities searching for Donna murder suspect
Donna police are working with the U.S. Marshals in the hunt for Fidencio Castillo, who is accused of shooting Efren Quiroz Saturday night at a Stripes convenience store.
The murder happened just after 9 p.m. at the Stripes off the expressway in Donna.
On Monday at about 1 p.m., Donna police raided Castillo's home. During an interview with Castillo's uncle, police learned Castillo's mother had a relationship with Quiroz, possibly prompting the murder.
Donna police say Castillo is driving a 2008 blue Dodge truck.
Castillo has a criminal history.
Anyone with information about Castillo's whereabouts is asked to call Donna Crime Stoppers at 956-464-8477.
