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

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

Seven deputies put on leave after Tamarac triple homicide; Nathan Gingles arrested for the murders and kidnapping.

Five Broward Sheriff's deputies have been put on administrative leave with pay pending the outcome of an investigation.

The sheriff said the deputies failed to take actions that could have prevented three deaths. “There will be people that will lose their job over this,” he said.

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.
