Summary based on the NamUs case record (MP53262) and 7 other sources
Frank K. Conlon, a 58-year-old man, vanished from his home in Nashville, Brown County, Indiana, on or around May 1, 1964. At the time of his disappearance, he was employed at the Allison Plant Division for General Motors in Indianapolis. Conlon had a background in law enforcement, having previously served as a police officer for the Army at Camp Atterbury, Indiana. The circumstances surrounding his disappearance are deeply concerning, with authorities suspecting foul play. It is believed that he may have been forcibly taken from his residence and transported to another location within the state, where he was possibly killed. This theory is supported by the fact that there has been no activity on his social security number since he was last seen.

Described as a white male with brown hair and hazel eyes, Frank Conlon stood between 5 feet 9 inches and 5 feet 11 inches tall and weighed approximately 160 to 180 pounds. He wore glasses and had a distinctive scar on the webbing of one of his hands, though it is not known which hand. He was a man with a thin build who also wore a full set of dentures. The case of his disappearance is complicated by the fact that the original police report has been lost over the years, making the investigation more challenging for law enforcement.

The investigation into Frank Conlon's disappearance remains open, handled by the Indiana State Police. Despite the passage of decades, his case is classified as a suspected homicide, and he is presumed to be deceased. The lack of any new leads or evidence has left his family without answers for many years, though in recent years, family members, including a granddaughter, have been actively seeking information about his fate. The overview of this case reveals a man who served his country and was a working member of his community before he was abruptly and violently removed from his life. The belief that he was abducted from his home and murdered elsewhere has been the prevailing theory for investigators, yet without a crime scene or the recovery of his remains, the full story of what happened to Frank Conlon in the spring of 1964 remains untold.
