Tyler David Collins, 29, turned himself in to authorities on Sept. 26 at the Rohnert Park Department of Public Safety Main Station at 500 City Center Drive.
Collins allegedly brandished a firearm at another person on the Copeland Creek Trail near Snyder Lake on Sept. 22 at noon. Responding police officers could not immediately locate any suspect in the area, so the decision was made to lock down the nearby campuses of Rancho Cotate High School, Lawrence Jones Middle School and Richard Crane Elementary School. The lockdowns lasted for about 45 minutes, according to a news release from Rohnert Park Police Deputy Chief Kevin Kilgore.
