CCTV images have been released of a child hostage situation in an Oklahoma supermarket, which ended with a policeman shooting dead the suspect.
The surveillance video released by police in Midwest City shows a man snatching a two-year-old girl from a shopping trolley and then holding a knife to her throat.
The toddler's mother, Alicia Keating, frantically pleads with the man, identified as Sammie Wallace, 37, as other shoppers crowd around.
She is seen and heard calling 911 for help. Local police are quickly on the scene and clear the store.
After 30 minutes of tense negotiation, police said Wallace began talking about a satanic cult and counting down from 60.
One of the officers, Captain David Huff, determined that the only way to ensure the safety of the toddler would be to take drastic action.
On the video he is seen moving quickly towards the hostage-taker and preparing to fire a single shot at his head.
The pictures stop at that point, but the police commentary continues and confirms Wallace was killed. The child was unharmed.
"Obviously, our goal was to talk him down to get him to release the child," Police Chief Brandon Clabes told reporters.
"I mean, we waited until the last second to use deadly force. No one wants to take a life, especially in the line of duty."
The Oklahoma County district attorney said the shooting on June 17 was justified, and hailed Captain Huff as a hero.
Wallace served time in a Texas prison from 2000 to 2011 on drug and assault charges. He was known to have a long history of mental illness.
