A Texas sheriff said a second video of deputies fatally shooting a man whose hands were raised appears to show him carrying what investigators believe was a knife.

Bexar County Sheriff Susan Pamerleau said at a news conference Wednesday that the video has been forwarded to the state crime lab to see if the footage can be blown up and slowed down. She said investigators believe 41-year-old Gilbert Flores was holding a knife, but it's unclear.

A motorist captured video that was released publicly which shows Flores standing motionless with his hands raised in apparent surrender when he was shot. A utility pole obscured one of his arms, however.

Pamerleau says the second video shows that both of Flores' arms were raised when he was killed.
