Nuno F.G. Loureiro, 47, was found Monday night at his house in the upscale Boston suburb of Brookline. He was taken to the hospital with gunshot wounds and was pronounced dead on Tuesday, the Norfolk District Attorney’s office said.

The DA’s office said the homicide investigation is ongoing.

Authorities have investigated whether his death could be connected to this weekend’s Brown University shooting and, at this point, a senior law enforcement official briefed on both cases told ABC News there is nothing to suggest they’re connected.
