A Florida man who authorities say accidentally struck members of his gay mens chorus with a pickup truck during a Pride parade over the weekend has offered his sincere regrets for the tragedy, which left one man dead.

Fred Johnson Jr., a member of the Fort Lauderdale Gay Mens Chorus, was awaiting the start of Saturdays parade in Wilton Manors, just north of Fort Lauderdale, when his vehicle accelerated unexpectedly, striking the three men, police said.

James Fahy, 75, was killed, while Jerry Vroegh, 67, and Gary Keating, 69, who is the choirs founding director, both suffered injuries, police said.
