Woman convicted in antifreeze deaths dies

LAWRENCEVILLE -- The former Forsyth County 911 operator who killed her husband and boyfriend by poisoning them with antifreeze -- and was also briefly implicated in the 1999 death of a Buford man -- died in prison Monday.

Lynn Turner, 42, was found unresponsive Monday in her cell at Metro State Prison in Atlanta and could not be revived, Georgia Department of Corrections officials said.

Turner was convicted in 2004 of killing her husband, Cobb County police officer Glenn Turner, in 1995. Authorities first thought he died of natural causes, but reopened the investigation in 2001 after her boyfriend, firefighter Randy Thompson, was found to have been poisoned.

Turner was also investigated in the 1999 death of Buford resident and Forsyth County Sheriff's Office Maj. Ronald Casper before his body was exhumed in 2002 and it was found he died of a heart attack. Turner, then a 911 operator, worked in the same office with Casper.

Turner, however, was serving a life sentence after a jury found her guilty of poisoning Turner and Thompson with ethylene glycol, an odorless chemical in antifreeze.

Georgia Bureau of Investigation spokesman John Bankhead told the Associated Press that an autopsy revealed no indication of foul play in Turner's death Monday, though the convicted murderer's mother seemed to think otherwise.

"As I started to leave (from a visit with Turner on Sunday), she said, 'Momma, those girls are going to get me. I just know they will," Helen Gregory told the AP.
