From Post Gazette 2012:
“The case of Emily Isabell Johnson remains unsolved.
Investigators believe Emily Isabell Johnson knew her killer.
Twenty years ago this week, Johnson was fatally shot in the back of the head in the kitchen of her Butler County home.
While the case remains unsolved, state police hope a new DNA test under way could reveal the killer's identity. Previous testing was inconclusive, but state police say the latest DNA tests can work with even smaller amounts of evidence.
Investigators believe the Clinton woman knew her killer because she trusted the shooter enough to allow him or her to stand behind her while she washed dishes.
Trooper Frank Jendesky Jr. said it appears that Johnson, 36, was shot Wednesday, June 6, 1990, or the next day, but her body wasn't found until that weekend.
Johnson was such a reliable employee that when she didn't report or call off from her job at J&L Specialty Products at One PPG Place, Downtown, police were asked to check on her.
Her doors were locked, and the windows were intact.
Johnson "didn't appear to drop anything" when she was shot, and there was no sign of a struggle, Jendesky said.
One of Johnson's nephews thinks she died because someone was jealous.
"In my heart, I believe it was a jealous rage," said Robert Gary, 57, a patrolman for the Bethel Park Police Department.
A U.S. serviceman stationed in Alaska was planning to visit her, and Gary believes the shooter found out about it.
"This was a jealous rage by someone who wanted to be a suitor and concluded if I can't have you, no one will," Gary said.
He said Johnson, who was his mother's half sister, was raised in Alliance, Ohio. She lived in Library before getting divorced and moving to Butler County in 1988. Her ex-husband has since died.
She bought the house and settled into rural life, owning a quarter horse and its foal, Gary said.
"They were the love of her life," he said.”
