Santa Clarita Valley Sheriff’s Station deputies responded to a domestic violence call resulting in deputies finding a grenade and conducting an hours-long search Monday night. Deputies responded to a report of a spousal assault on the 17300 block of Sarita Avenue, in Canyon Country, around 5:30 p.m. The suspect allegedly hit his girlfriend, who is nine months pregnant, and then apparently fled the scene. When deputies responded, they had information leading them to believe the suspect might still be on the premises, so an aerial unit was called, as well as a K-9 unit to search for the suspect.
