Seven Broward Sheriff’s Office deputies have been placed on administrative leave as an internal affairs investigation commences over a triple shooting in Tamarac.

Broward Sheriff Gregory Tony angrily announced Wednesday that seven deputies and detectives were being placed on administrative leave after reviewing their investigative actions in the case of a Lauderhill man who for months had threatened to kill his wife before being charged with her violent death and that of two others over the weekend.

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

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