Robstown police arrested an 18-year-old man on charges of possession of a controlled substance after executing a search and arrest warrant Friday.

Robstown police Sgt. Derley Flores said police received calls from the public about the activity of Abelardo Cedillo at the home he was staying in, located in the 100 Block of Curtis Place.

As a result, officers began an investigation into the citizens' concerns and obtained a warrant to search Cedillo's home and place him under arrest, Flores said.

Upon arriving at the home, Cedillo surrendered peacefully to authorities and informed them of where he had hidden his drug stash. He also later gave a voluntary confession, Flores said.

Police found numerous small bags filled with cocaine, as well as a small amount of heroine. Officers also discovered .22- and .380-caliber bullets in the home, though a weapon was not located, Flores said.

"He claimed that he'd gotten rid of it a while back, but we didn't find one at the home," he said.

Flores said Cedillo was already on probation for an incident earlier this year in which he was charged with deadly conduct for allegedly shooting at a home on Kansas Street.

Cedillo's girlfriend, an infant and Cedillo's brother were also in the home at the time of Cedillo's arrest, but the two adults were not arrested, Flores said.

Cedillo is facing one charge of possession of a controlled substance for the cocaine, a second-degree felony, and another charge of possession for the heroine, a third-degree felony, police said.

As a felon on probation, he will likely face enhanced penalties for possession of the ammunition found in his home, as well as the fact the home the drugs were discovered in is near San Pedro Elementary School, Flores said.

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