An alcoholic father was drowned in an attempted ‘exorcism’ after his son decided to confront the ‘demon’ he saw in his father’s eyes, a Massachusetts court has heard.
Jack Callahan, 22, has gone on trial at at Plymouth County Superior Court for the murder of his father Scott, 57, who was found by police floating in a pond outside Duxbury, around 30 miles outside of Boston, in June 2021.
The then 19-year-old told police his banker father was possessed by a demon called ‘Dirty Dan’ who he thought could be destroyed through baptism.
Callahan was bringing his father home from a Boston bar when his mother, Wendy, called to say she would not have her ex-husband in their house, and the young man asked their cab driver to pull over next to the pond.
He grabbed his father and repeatedly plunged his head under the water, telling cops: ‘I left him there to decide, you can come to heaven with me or hell. I think he chose hell.’

Scott Callahan’s obituary reported that he was the Senior Vice President of Texas Capital Bank, and had an ‘extensive career in finance’.
He had been receiving treatment for alcoholism at a center in Hopkinton before he checked himself out and headed for the bar in Boston.
The teenager called an Uber to bring him back to the $1.5 million home in Duxbury and said his father began to attack him when he asked the driver to pull over at around midnight.
‘He indicated that the victim had been punching him in the face,’ Plymouth Assistant District Attorney Shanan Buckingham said at Callahan’s 2021 arraignment.
‘He went on to state that in this incident at the pond, he believed he was baptizing his father.
‘He described that he was holding his father in the pond on his back like a baby, that he continually dunked the father’s head in the water about four to eight times, that when the father started to cough and choke, he would lift his head up.
‘And then when the father started to fight and strike him, he would push the head back into the water.
‘He did so until his father was no longer struggling and floating.’

The teen’s mother saw him finally arrive home in soaking wet clothes at about 2am when she called police to tell them he was having a mental health episode and her ex-husband was missing.
‘The mother indicated that the defendant had not exhibited this behavior before and that he had no history of mental illness,’ Buckingham said.
Police called an ambulance after finding Callahan ‘worked up and distraught’, hyperventilating and passing out.
He told them his father hit him, and he did not know where he was: ‘He’s missing. I don’t know what happened. I blacked out.’
He eventually directed the police to Crooker Memorial Park where officers found Scott in Island Creek Pond.
