Authorities say a Lantana man shot and killed is ex-girlfriend and then killed himself.

The Palm Beach County Sheriff's Office reports that 47-year-old Russell Antonio Dillard and 33-year-old Sarah Covington Crews had been broken up for about six months when Crews stopped at Dillard's home Saturday to retrieve some belongings. She then went to a friend's home two doors down.

About two hours later, authorities say Dillard went to the friend's home and fatally shot Crews. The friend called 911 while Dillard ran back to his home.

SWAT teams and negotiators were called to the scene. When authorities finally entered the house, they found Dillard dead.
