A welcome home turns deadly for an Elizabethtown woman found shot to death in her home Sunday night.
Hardin County police say the victim's husband just returned from Iraq last week, now police say her mother-in-law may have pulled the trigger.
Police are calling it a complicated case because the victim's mother-in- law, who's now the main suspect, is in an advanced stage of Alzheimer's disease. Her son is the one who called police to tell them he believed his mother had killed his wife.
"He was probably just ready to come home and be with his wife and son. This is just tragic to happen to him," says Virgil Willoughby with the Elizabethtown Police Department.
He had only been home for three days, on temporary leave from his tour in Iraq, when he made a 911 call that his wife was dead.
"They found a dead body laying in kitchen and she'd been what appeared to be shot a couple of times," said Willoughby.
39 year old David Peterson was the one who called police. He told them his wife, Carlotta, was shot by his mother, 74 year old Harietta Stewart. Stewart lived in the home with Carlotta and according to police she suffers from stage three Alzheimers.
Willoughby says, "It's a little unique based on the fact that it's a family related issue and on top of that, we're talking about someone with a severe form of Dementia. Her cognitive skills are diminished so interviewing this subject has been challenging."
Police aren't commenting on how Stewart may have gotten a hold of a gun, but a Louisville T.V. station is reporting Peterson told them a gun was hidden in the home and somehow, Stewart found it.
According to reports, Stewart is now in the care of adult protective services. Police say the investigation is still pending, but under the circumstances, it is uncertain if any charges will be filed.
The couple also has an 11 year old son who was not home at the time of the shooting.
