ROUSES POINT, N.Y. (AP) _ A man killed in a car bomb explosion may have been targeted because he was about to testify in a Canadian drug investigation, his father said.

Lee Carter, 31, died in the blast Wednesday morning, authorities said. He was in his sports car behind a bowling alley where he worked as a bartender when the blast occurred.

The nature of the explosive wasn't immediately known.

Carter lived nearby in a mobile home in this community on the Canadian border 185 miles north of Albany.

Lee Carter Sr. said his son was an informant in a drug investigation and was to testify in Quebec and felt he was in danger.

State police said they were investigating the bombing along with the FBI, the Federal Bureau of Alcohol, Tobacco and Firearms and Quebec police.

State Police Capt. Ronald Tritto wouldn't comment on whether Carter was an informant. He said Quebec police were involved because of their expertise in explosives and bombs.
