Patricia Margaret Sullivan, known as Patty, was 35 when she vanished from Butte, Montana on November 25, 1992, the day before her 36th birthday. She had recently completed an alcohol treatment program and was staying with her sister in Missoula. On Thanksgiving she traveled with her sister and the sister’s boyfriend to Butte to see their mother. While the companions went into the house, Patricia stayed in the car and was gone when her sister checked moments later.

Investigators established that Patricia later visited two Butte bars that evening. After leaving her mother’s house she went to Muzz and Stan’s Bar, asked for a ride to Harrington’s Bar, was seen inside Harrington’s, and left with an unknown man — the last confirmed sighting. Rumors later circulated that she had been taken to Idaho and murdered, but no concrete evidence has been confirmed. Patricia was a mother of two daughters and remained close to family despite struggles with alcohol.

If anyone knew Patty or was in Butte that night, what did you see or hear that might help explain what happened to her?
