FBI investigates fatal beating of man by deputies; video evidence may have been destroyed

The FBI has launched an investigation into the beating death of a man by sheriff's deputies in Kern County, California. Two cellphones that contained video evidence at one point no longer contain the videos that show officers beating David Silva to death with batons on the head, "even after he was lying motionless on the ground." The deceased was 33, and a father of four. “Our credibility is at stake here,” said Kern County Sheriff Donny Youngblood “I have seen the video. I cannot speculate whether they acted approriately or not just by looking at the video.” More: Los Angeles Times.
