Officials have identified the man they found dead in a room at the Braintree Motel 6 as Tizaya Robinson, 25, of Boston.
In 2008, then a 17-year-old from Jamaica Plain, Robinson was stomped into unconsciousness outside a party in Marshfield, in an incident that brought national headlines.
Robinson, who was black, was surrounded and beaten, kicked and stabbed repeatedly with a stick by seven white Marshfield residents who attacked him while yelling racial epithets - and who kept yelling the slurs even as police arrived and began arresting them.
The attack left him with long-lasting nerve damage in a hand and foot.
Four pleased guilty; three went to trial and were found guilty of charges that included violating Robinson's civil rights and sentenced to between three months and three years behind bars in 2011. In 2015, the Supreme Judicial Court upheld their convictions on the civil-rights charges.
The Norfolk County District Attorney's office and Braintree Police report Robinson was staying at the Motel 6 and that officers approached his room with caution Friday night because he had warrants from Dorchester Municipal Court charging him with domestic assault and battery and attempted kidnapping. Authorities say Robinson opened fire from inside the room, hitting Donald Delaney in the head. A robot sent into the room later found Robinson dead, likely from a self-inflicted gunshot wound, authorities say.
