INDIANA, Pa. (KDKA/AP) – Pennsylvania authorities say a Minnesota man has been arrested on charges he killed a 76-year-old Pennsylvania woman a quarter-century ago.

Indiana County District Attorney Patrick Dougherty says the suspect is a 61-year-old man from Magnolia, a tiny town of roughly 200 people in Minnesota.

The headline in the Minnesota Star Tribune reads: “Minnesota Town Wonders Whodunnit In Supposedly Solved Cold Case.”

Dougherty says the suspect fired two shots through a window that killed Myrtle McGill in the kitchen of her White Township home. Her body was found Dec. 13, 1991, but authorities believe she died several days before.

A sliding glass door had been smashed by a rock, but the house was not ransacked

“We did notice multiple gunshot holes through the front windows of the house, so the perpetrator apparently was in the front area of the house and saw the victim apparently in the kitchen,” said Tom Streams, the Indiana County coroner in 1991.

Authorities say her car was stolen but nothing else.

The 1982 Ford LTD was located four days before McGill’s body was found. It had been parked near the Greyhound bus station in Pittsburgh.

The car yielded no clues, no usable fingerprints and no witnesses.

Dougherty and state police aren’t revealing the suspect’s name or other details until a news conference Friday.
