Officers arrived at the father and son's home within an hour of the alleged stabbing, according to a statement from the Suffolk County Police Department.
About 20 people were tuned in to a Zoom conference call just after noon on Thursday when 72-year-old Dwight Powers unexpectedly slumped from his chair and disappeared off-screen.
Police were reportedly delayed about 15 to 20 minutes because the chat participants didn't know Powers' exact address.
Several participants in the virtual chat called emergency authorities, police said, as the horrific events unfolded. One witness told WABC that they saw Scully-Powers lay a bedsheet on the ground as if to cover something.
"People thought he might have been attacked", a police spokesman said. One witness, who was not identified, calls what they saw weird.
A Long Island man was stabbed to death by his son while he participated in a Zoom meeting, authorities said.
Because he was still being treated, Scully-Powers did not yet have a court date, they said.
He was charged with 2nd-degree murder and was transported to a local hospital for minor injuries he sustained while jumping out of a window, police said.
Thomas Scully-Powers, 32, is in custody, accused of killing his father. Police reported a "nick" on Scully-Powers' wrist.
Once they figured out the victim's name and address, they called 911.
