A Westmont man was charged July 11 with one felony count of unlawful use of a weapon after allegedly firing a gun on Cass Avenue, authorities said.

Police were dispatched about 10:12 p.m. to the 100 block of North Cass Avenue for a report of possible gunshots and a male wearing dark clothing running from the area, authorities said.

Police found a man, later identified as Daniel C. Mainz, who matched the description near Holy Trinity Catholic Church.

Shell casings were recovered in an alley in the 100 block of North Cass Avenue and a handgun was later recovered in the zero to 100 block of East Dallas Street, police said.

Mainz, 18, of Westmont was taken into custody and transported to the DuPage County Sheriff’s Office to await a bond hearing. The DuPage County State’s Attorney’s Office may add additional charges once the investigation is completed, authorities said.
