Dr Richard Field, 49, and his fiancé Dr Lina Bolanos, 38, were murdered in cold blood in their penthouse in South Boston.
The pair were brutally killed in their own home last Friday night at approximately 8:45pm.
Police told the Boston Globe that the couple’s hands were bound and their throats slit open.
One of the officials also said that the killer had written a message of retribution on the wall and photographs of the pair had been cut up.
Dr Richard Field sent a text to a friend pleading for help on the Friday night, but by the time police arrived it was too late.
At the scene of the crime, authorities were confronted by 30-year-old Bampumim Teixeira, who opened fire on them.
“This individual had just killed two people,” Boston Police Commissioner William Evans said. “He had nothing to lose.”
Police shot back at Teixeira, who survived the hit and was taken to hospital.
It’s believed Teixeira knew the couple but the police haven’t established a motive for the crime yet.
Police said multiple charges are expected against Teixeira.
