Police in San Antonio, Texas, said Wednesday that a new video purportedly shows a man killed by officers might have been holding a knife when he was fatally shot. The new footage appears to show Gilbert Flores, 41, with his hands up but also while holding what appears to be a knife, authorities said. Police did not release the second video or reveal the source. An earlier video shot by a witness shows Flores with his hands up before he was shot, but with one of his arms obscured from view. Two officers were responding to a domestic dispute when they discovered Flores outside his home. The officers said a woman inside the house had a gash on her head and was holding a baby who also appeared to be injured. The officers were placed on administrative leave while the incident is under investigation.
