2 found dead in Boston penthouse apartment, suspect in custody

— -- Two doctors were found dead Friday night in a penthouse at a luxury apartment building in Boston where a suspect was shot after a violent struggle and an exchange of gunfire with officers, according to police.

Officers responded to a 911 call about a gunman at the Macallen Building in South Boston on Friday around 8:38 p.m. ET. Upon arrival, the officers entered the building and saw a male suspect armed with a gun at the door of a penthouse, according to the Boston Police Department.

The suspect immediately began firing at the officers when they confronted him, causing authorities to fire back, police said. The suspect was shot multiple times and, after a violent struggle, was placed in custody and transported to a hospital for non-life threatening injuries, police said.

The suspect has been identified as Bampumim Teixeira, 30, of Chelsea, a city across the Mystic River from Boston. Multiple charges will be finalized and sought against him in South Boston District Court, according to the Boston Police Department.

No officers were struck by gunfire, but several were transported to local hospitals for non-life threatening injuries, police said.

Police found a man and a woman suffering from traumatic injuries inside the 11th floor penthouse, and they were pronounced dead at the scene, police said.

They were later identified as as Richard Field, 49, and Lina Bolanos, 38, both of Boston.

Field worked at North Shore Pain Management, which described him as "a guiding vision" there and "instrumental in the creation of this practice."

"Dr. Field was noted for his tireless devotion to his patients, staff and colleagues," NSPM said in a statement.

Bolanos was a pediatric anesthesiologist at Massachusetts Eye and Ear.

"The entire Mass. Eye and Ear community is deeply saddened by the deaths of Dr. Lina Bolanos and her fiancé," John Fernandez, President and CEO of Mass. Eye and Ear wrote. "Dr. Bolanos was an outstanding pediatric anesthesiologist and a wonderful colleague in the prime of both her career and life."

Police described the incident as a double homicide and said the investigation is ongoing.

At a press conference Friday night, Boston Police Commissioner William Evans told reporters they believe the suspect and the victims knew each other.
