Monterey County Sheriff’s deputies arrested 2 men on gun charges Friday night. As deputies responded to the Las Palmas/ Indian Springs area to investigate reports of gunfire at the river, the officers heard continuing gunshots. A short time later the deputies stopped a car leaving the area. A search of the vehicle uncovered a large-caliber semiautomatic assault rifle without a serial number, and loaded magazines. Pablo Perez and Ronaldo Lopez-Hernandez were arrested and booked into Monterey County Jail.
