Robstown police last week executed a search and arrest warrant that resulted in the arrests of a husband and wife after officers allegedly found black tar heroin in the couple's residence.

Police executed the search and arrest warrant on March 30 at an apartment above the Texican Convenience Store, located in the 1000 Block of Iowa Street. Police said 36-year-old Gilbert Cervantes and his 29-year-old wife, Lucera, were in the home at the time of the search.

Officers seized two bottles of methadone and nearly three grams of black tar heroin, which was found hidden in the couple's bedroom. Assorted drug paraphernalia, including scales, syringes and baggies, was confiscated by officers, including $769 in cash, according to the report.

Narcotics Officer Eddie Valadez said the convenience store that the apartment was situated above was also the site of an arrest last month of a City of Robstown Public Works employee for possession of cocaine and dangerous drugs.

Valadez credited an anonymous tipster for providing crucial information to the department's hotline on March 1, which resulted in the arrest that same day.

Valadez said police found 23-year-old Tomas Alvarado inside the store, where he was a part-time employee, with nearly 25 grams of cocaine. Some unidentified pills were also discovered on Alvarado's person, Valadez said, and have been submitted to the Texas Department of Public Safety for testing.

Alvarado, who was working for the Public Works Department at the time and has since been terminated, was placed under arrest and transported to the Nueces County Jail, Valadez said. He is facing one felony count of possession of cocaine and dangerous drugs, a state jail felony.

Gilbert and Lucera Cervantes are both facing one felony count each of possession of a controlled substance and possession of a substance.

Anyone with information on suspected drug activity, and would like to remain anonymous, is asked to contact the Robstown Police Department's hotline at (361) 387-TIPS.
