Police shot and killed a man who snatched a two year old from a shopping cart at an Oklahoma Walmart.   The surveillance video of the June 17 incident has been released. 

Police say the suspect Sammie Wallace was high on drugs when he took the child  while her mother, Alicia Keating, had her back to the shopping cart. Keating began to scream and pleaded with the suspect to return her daughter. Wallace held the little girl at knife point for about half an hour.

Police say Wallace was uncooperative and the situation quickly deteriorated, with the suspect making odd demands. The tipping point came when Wallace started a 60-second countdown with the knife at the child’s neck.

While an officer distracted Wallace,  Capt. David Huff moved in and fired a single deadly shot at his head.

The toddler was not hurt and returned to her mother.
