Prosecutors say police in August seized electronic devices from Sheehan’s home that contained hours of video footage of Sheehan sexually abusing a child who appeared to be asleep at Sheehan’s home.

Authorities say the assaults happened over multiple days and that the child was 11-and-12-years-old at the time.

Sheehan previously coached Norwell youth football. His lawyer didn’t immediately comment.

The Patriot Ledger reports Norwell police began looking into Sheehan in June after a child reported he assaulted them in another town last August.
