Authorities are investigating a triple homicide involving a Florida man who was the subject of an Amber Alert issued for his young daughter last weekend. 

Nathan Gingles, 43, was charged with three counts of first-degree murder after he was accused of kidnapping his 4-year-old daughter, Seraphine Gingles, Feb. 16.

While the girl was later found safe, her mother, grandfather and a neighbor were killed. 

In one incident, Mary had called deputies in December and said her husband was threatening to kill her. Tony said that a deputy responded and spent over 30 minutes gathering information from Mary and may have had enough evidence to arrest Gingles but did not arrest him. 

“We could have done more. … I’m not shying away from holding us accountable,” Tony said at the press conference. “We’re not just looking at isolated incidents. We have a robust list of all the calls for services that occurred at that site location either coming from the husband or coming from the wife.”

Mary’s divorce petition also states that Nathan is “ex-military and has high security clearance,” according to the Miami Herald.

“I don’t want the public to lose faith,” Tony added at Wednesday’s press conference. “When we rectify this situation, I’m going to send the fear of God amongst this entire agency.”

The Broward County Public Defender’s Office, which a judge appointed to the case, did not immediately respond for comment on behalf of Gingles.
