MIT professor Nuno Loureiro was killed in a shooting at his home in Brookline, Massachusetts Monday night, the school confirmed. Loureiro, a nuclear science and engineering professor from Portugal, was 47 years old.

A Brookline police spokesperson said officers responded to a call for gunshots at an apartment on Gibbs Street at about 8:30 p.m.

"A victim was located who had been shot multiple times," Brookline police deputy superintendent Paul Campbell told WBZ-TV.

Loureiro was taken by ambulance to a Boston hospital, where he died Tuesday morning. No other information about the shooting was immediately released and authorities did not say if they are looking for a suspect. Campbell said no one is in custody.

"This is an active and ongoing homicide investigation," Norfolk County District Attorney Michael Morrissey's office said in a statement.
