CANYON COUNTRY – A 34-year-old man was arrested on suspicion of assault and negligently firing a gun during a fight, a sheriff’s official said Wednesday. Everardo Alvarez got into a custody dispute with his child’s stepfather shortly before 11p.m. Tuesday in the 17700 block of Scherzinger Lane in Canyon Country, said Sgt. Darren Harris of the Santa Clarita sheriff’s station. During the fight, the stepfather suffered a serious cut on his head, and Alvarez’s gun was fired, although no one was hit, Harris said. Investigators are trying to determine whether Alvarez hit the stepfather with the butt of his gun and whether the gun was discharged during the struggle or in some other way, he said. Alvarez, who is being held in lieu of $30,000 bail, was booked on suspicion of assault with a deadly weapon and misdemeanor gross negligent firing of a gun, Harris said. The victim was hospitalized with wounds that are not life-threatening, Harris said.
