Paul Leopold Siegler was living in Concord, NH at the time of his disappearance in 1996.

Paul grew up in Concord, NH and graduated from St. Paul’s School in 1959.

"I couldn't have had a better dad." - Brandyn Siegler, Paul's son.

Paul participated in a NASA study in 1976 that was advertised as a weightlessness experiment. When he returned home from the study, according to his son, Brandyn, he had changed, claiming that his father had developed symptoms of paranoid schizophrenia. In the late 1970s, Paul and his son moved back to Concord, NH into a home that was gifted to him by his grandmother. By the time Brandyn graduated from high school, Paul had moved out of the home to live with friends and coworkers. Around this time, Paul moved to a tent he had set on a friend’s property, a stretch of land near the Merrimack River. He was struggling with homelessness at the time of his disappearance and was actively trying to find shelter from the cold.

Paul was last seen at a phone booth in November of 1996.

Paul was last seen at a phone booth at the former “Bear Right” in Concord, NH on November 15, 1996 by his son, Brandyn, who reported that his father was “blessing everyone, calling them angels” and seemed to be in good spirits, though he was off of his medication. This was the last time anyone has seen or heard from Paul.

Paul was reported missing in early 1997 by his son. Shortly after he was reported missing, a search of the area that he was last seen in was conducted. According to reports, Paul’s tent was found set up along the Merrimack River. Inside, authorities found his bible, which he was known to carry with him everywhere he went.

Where the case stands today.
