Fired employee kills boss, co-worker, police say

PORT ST. LUCIE, Fla. (AP) -- A man suspected of killing his boss and a co-worker after losing his job was being sought today by authorities who feared he had his young daughter with him.

Mario Betancourt, 43, allegedly went to his van Monday afternoon, grabbed an automatic handgun and walked back into The Padding Store where he opened fire, police spokesman Chuck Johnson said.

The gunman yelled, ''You won't make my day miserable now!'' as he fled, said Andy Martin, manager of Scott's Tire next door.

Police said Betancourt likely had his 10-year-old daughter, April, with him.
