He was released on his own recognizance.

Police also arrested Gilberto Maciel Sedano, 27, and Alvaro Bisarro Gonzales, 28. Sedano is charged with possession of controlled substances within 1,000 feet of a school, an illegal-drug-stamp tax violation and possession of controlled substances, all third-degree felonies.

Gonzales is charged with possession of drugs within 1,000 feet of a school and a drug-stamp tax violation. Bail was set for Sedano and Gonzales at $10,000 each.

The fourth defendant, Shanna L. Gonzales, 26, is charged with possession of drugs within 1,000 feet of a school and an illegal-drug-stamp tax violation.
