A troubled Glynn County, Ga., police lieutenant is dead after a SWAT standoff at his home. Two others were also killed in McIntosh County, authorities confirmed Friday morning.

Robert Cory Sasser, 41, had been arrested last month after his estranged wife said he threatened to kill her and her guest while trying to kick in her door, according to our Florida Times-Union news partner.

He was charged with simple battery and criminal trespassing and put on administrative leave without pay.

They had been separated for three months, and Sasser told officers he was there to get the keys to their vehicle. Preliminary indications are that the wife and her boyfriend were shot Thursday night in McIntosh County during a confrontation with Sasser that involved an exchange of gunfire.

Sasser fled back to his home Glynn where a SWAT situation ensued and ended with his death. Authorities did not say if he killed himself or was shot by officers. Neighbors said he was parked in the driveway and refused to get out of his truck. The back window was shot out. More information is expected to be released later today.

Sasser was released on bond after his May incident but was arrested again after another police standoff in the woods in Glynn County. He was charged with possession of a gun.

Sasser also was investigated by the Georgia Bureau of Investigation following the June 2010 shooting death of 35-year-old Caroline McGehee Small after a chase in Glynn County. He and Officer Todd Simpson fired eight bullets into the unarmed woman’s car after the chase, neither checking her condition as their patrol car cameras recorded them discussing their shooting skills, according to the bureau’s 540-page case file. The woman was declared dead a week later.
