Possible Ex-Policeman Kills 3 in Store Robbery

A man who said he was a police officer who had been fired herded six people to the back of a grocery store, stacked them by twos and began shooting and stabbing, police said. Three people were killed and two were badly hurt.

Officials said the motive was robbery but declined to say what was taken. They were searching for a 20- to 30-year-old man.

An all-points bulletin prompted calls from police departments around the nation with information about recent firings after officials ruled out former local officers as suspects.
