DALLAS (AP) — A second video that captured Texas deputies fatally shooting a man whose hands were raised appears to show that he was holding a knife, a sheriff said Wednesday, declining to release the video because the investigation is ongoing. Bexar County Sheriff Susan Pamerleau said at a news conference that the video has been forwarded to the Texas Department of Public Safety's crime lab to see if it can be blown up and slowed down to establish the sequence of Friday's events. A separate video of the shooting taken by a motorist and released publicly shows Flores raise his arms in apparent surrender and stand motionless just before the two deputies opened fire, killing him.
