2 deputies killed, suspect and 2 others dead in shooting at North Carolina home

Police believe a gunman killed two sheriff's deputies, his mother and his stepfather at a North Carolina home before killing himself Wednesday. The shooting sparked a lengthy standoff between the gunman and authorities in Boone, North Carolina, that ended late Wednesday night.

The Watauga County Sheriff's Office identified the deputies as K-9 Deputy Logan Fox and Sergeant Chris Ward. Sheriff Len Hagaman identified the two other victims as the gunman's mother and stepfather, a reporter for CBS affiliate WBTV posted to Twitter. "This is an incredibly tragic situation and our thoughts and prayers are with everyone involved as well as their families and our community," Hagaman said in a statement.
