Today, after an 8- day trial, a jury deliberated approximately 25 hours before finding Jack Callahan, now 22, guilty of one count of Involuntary Manslaughter. The Commonwealth charged Callahan with one count of Murder. Sentencing is scheduled for next Friday, May 3rd.

At approximately 2 a.m. on June 28, 2021, Duxbury Police received a call to report that Jack Callahan, then 19, was acting erratically and that his father, Scott Callahan, 57, was missing in the area of Island Creek Pond at Crocker Park.

At approximately the same time, Duxbury Police and Fire personnel responded to Island Creek Pond at Crocker Park and located Scott Callahan submerged in the pond. EMS performed life-saving measures and he was transported to Beth Israel Deaconess Hospital-Plymouth, where he was pronounced dead.

Duxbury Police contacted Massachusetts State Police Detectives assigned to the Plymouth County District Attorney’s Office and an investigation commenced. At trial, the jury heard evidence that Jack Callahan travelled to Boston to meet up and retrieve his father and return to Duxbury. The two took a ride-share vehicle home from Boston, and after midnight on June 28, the ride-share dropped the two men off in the vicinity of Island Creek Pond. There a physical altercation took place between the pair.   

The state Office of the Chief Medical Examiner found the cause of death was drowning and the manner was homicide. The OCME reported that Scott Callahan had water-logged lungs, and an abrasion on his head.
