DUXBURY, Mass. (WBZ NewsRadio) — A Duxbury man was ordered held without bail at his arraignment Tuesday morning in Plymouth District Court. Prosecutors said 19-year-old Jack Callahan believed he was exorcising his father of demons by baptizing him before he drowned at Island Creek Pond.
Jack Callahan, 19, has been charged with murder. His attorney asked the court that he be sent to Bridgewater State Hospital for mental health evaluation.
Duxbury Police received a call from Callahan's mother around 2 a.m. Monday stating that her son had come home and said his father was missing.
Authorities later pulled the victim, Scott Callahan, from the water and gave him CPR. He was taken to Beth Israel Deaconess Hospital-Plymouth, where he was later pronounced dead.
WBZ-TV reports Callahan told officers that his father stopped at the pond for a midnight swim, and then went under the water.
Callahan told investigators that he "saw" the "demons" in his father's eyes and began submerging him multiple times. After an investigation, police did not believe the man's story to be true.
Police said a fight had taken place between the two near the pond after the younger Callahan picked up his father from Boston in a rideshare. They said he kept submerging the man in the water until he did not fight back or float. They found Callahan "distraught and hyperventilating."
Callahan was arrested on Monday.
He is due back in court on August 12.
