On Sunday morning, a U.S. Army vet gunned down his wife, her father and a neighbor in a quiet Tamarac neighborhood, deputies say.

TAMARAC - A grieving relative of two victims killed in a Broward County triple homicide is holding both the Broward Sheriff's Office and the U.S. military responsible, questioning how the alleged shooter was allowed to remain free despite multiple domestic violence incidents.

Sheriff Gregory Tony said Wednesday that deputies and detectives failed to act on warning signs leading up to the killings.

A South Florida sheriff delivered a blistering rebuke of his own deputies this week, saying his department “failed” in its handling of a lengthy domestic violence case that he says culminated in a triple homicide.
