Two doctors have been found dead in a luxury penthouse in Boston – reportedly tied up and with their throats slit.

A suspect, named Bampumim Teixeira, is in custody after police exchanged fire with him while responding to reports of an intruder at the high-rise flats on May 5.

The bodies of anesthetists Richard Field and Lina Bolanos, engaged to be married, were found inside.

The suspect was in hospital with non-life threatening injuries.

According to police, a suspect fired at officers who were responding to a report of a man with a gun at a luxury high-rise in South Boston.

The officers apprehended Bampumim Teixeira inside the penthouse flat before discovering Dr. Richard Field, 49, and Dr. Lina Bolanos, 36, who were already dead, the Boston Globe reported.

A message of retribution was apparently written on the wall, an official told the newspaper. Their hands were tied and throats cut, the paper said.

Dr. Richard Field – who is from London, according to his Facebook page – reportedly texted a friend in a plea for help.

The motive is still unclear but police believe the victims may have known the suspect due to the building’s tight security.

Bampumim Teixeira was recently released from prison after serving nine months for bank robbery.

He was due to appear in court for his arraignment on May 8, according to Jake Wark, a spokesman for Suffolk County District Attorney Daniel Conley.

Dr. Lina Bolanos was a pediatric anesthesiologist at Massachusetts Eye and Ear while Dr. Richard Field worked at the Brigham and Women’s Hospital, an affiliate of Harvard Medical School.
