Police found Daniel Kerrigan, 70, unconscious in the kitchen of his Stoneham property on Sunday after receiving an emergency call reporting a “sudden death”.
The athlete’s brother, Mark – who was also at the house – was hospitalised for an unspecified injury, reports the New York Daily News.
According to a police report filed in court, the 45-year-old son attacked his father during an argument about whether he could use the phone.
On Monday (25Jan10), he was charged with assault and battery with a dangerous weapon on an elderly person and causing serious bodily injury.
Daniel Kerrigan’s cause of death is pending autopsy results.
