At about 4:05am Tuesday, Turlock Police Officer Aziz got out with four suspicious persons at the Aspiranet Turlock Family Resource Center in the 2100 block of Geer Road.
Aziz made contact with and identified the four, including Sonya Muzquiz, 33, of Turlock.
When Aziz had his dispatcher run the four, he discovered Muzquiz had a local misdemeanor bench warrant for possession of a controlled substance and possession of methamphetamines.
Muzquiz was arrested and a search incident to arrest led to the discovery of fentanyl.
Muzquiz was released on a citation on charges of possession of a controlled substance and her warrant.
