Lina Bolanos and Richard Field, both doctors in the field of anesthesiology, were found murdered in Field's $1.9 million penthouse condo in Boston, Massachusetts, on May 4.
According to the paper, Field sent out a final text, a plea for help, to one of his friends but by the time police arrived around 8:45 p.m., the couple was already dead.
"On arrival, the officers made entry to the building and observed a male suspect armed with a firearm", police said.
The suspect was identified as 30-year-old Bampumim Teixeira, who was recently released from prison after serving less than a year on a larceny conviction, Jake Wark, a spokesman for Suffolk County District Attorney Daniel Conley, told NBC News on Sunday.
Officers fired back and Teixeira was shot.
It is possible that the victims knew their assailant, as the condominium had tight security and there was a "message of retribution" written on a wall of the apartment, the Boston Globe reported.
"Hopefully, this guy that they caught will be able to say who he is and why this was done", Michael Gibbs, Bolanos' godfather, told the Boston Globe. "These are two well-respected people killed in their penthouse apartment". They were revealed to have their hands tied, and throats cute, say police.
While police try to determine the motive for the slaying, neighbors are questioning how Teixeira gained access to the 11th floor of the building.
Massachusetts Eye and Ear Infirmary released a statement addressing the death of Bolanos, who worked there as a doctor.
Prior to working at North Shore Pain Management, Field was an anesthesiologist and pain management specialist at Beverly Hospital and Brigham and Women's Hospital in MA.
Colleagues called Dr. Field a "tremendous advocate for his patients" and Dr. Bolanos "a wonderful colleague in the prime of both her career and life". He'll be arraigned Monday in South Boston Municipal Court. In both instances he passed the teller a note demanding money but never showed a weapon. He committed the same crime two years earlier.
