INDIANA, Pa. - A Minnesota man is behind bars, held in the cold-case murder of an elderly woman in Pennsylvania a quarter century ago.

Indiana County District Attorney Patrick Dougherty says the suspect is a yet-unnamed 61-year-old man from Magnolia, Minnesota, a tiny town of roughly 200 people just across the South Dakota border.

Dougherty says the suspect fired two .22 caliber bullets through a window that killed 76-year-old Myrtle McGill as she stood in the kitchen of her White Township home. Her body was discovered on December 13, 1991, but authorities believe she was murdered approximately a week earlier.

The Indiana Gazette reports that a glass sliding door to McGill's home was smashed with a rock, but the only item reported missing was her 1982 Ford LTD. The car was found Dec. 9, four days before McGill’s body was discovered, in the Greyhound bus station near Pittsburgh. No usable fingerprints were found in the vehicle.

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