Shortly after sunset, Boston police responded to the call about an armed and unsafe male suspect in District C-6.
Prosecutors were preparing murder charges on Monday in the brutal slaying of two engaged doctors at their penthouse apartment in Boston against the alleged killer - an ex-convict who authorities believe knew of the couple.
Evans identified the armed man as Bampumim Teixeira.
Both victims, who were bound and sustained trauma, died at the scene, prosecutors said. Lina Bolanos and Richard Field were found Friday night by cops at the Macallen Building in South Boston.
Police have said that the suspect was known to the victims, who were both anesthesiologists.
"There is no evidence at this stage of the investigation that there is any relationship between them", Conley said. They were both pronounced dead at the scene. He has been charged with two counts of murder, and authorities say that more charges could be handed down at a later time.
Officers arrived after Dr Field, who graduated from the University of Sheffield's Medical School in 1999, sent a text to a friend saying there was a "gunman" in his home.
At about 8:38 PM on Friday, May 5, 2017, officers assigned to District C-6 (South Boston) responded to a call for a person with a gun in the area of 141 Dorchester Avenue in South Boston. He has not yet entered a plea.
A man suspected of killing two engaged doctors in their luxury Boston condominium has been ordered held without bail.
An attorney pleaded not guilty on Teixeira's behalf to two counts of murder on Monday.
A judge agreed to seal some documents in the case for 90 days.
Pappas said police found a backpack near the front door that was filled with jewelry they believe belonged to Bolanos. He was wounded in the hand, abdomen and leg, prosecutors said Monday.
He will next appear in court on June 8.
His arraignment is scheduled for early Monday afternoon at Tufts Medical Center. The court is expected to appoint an attorney for him then.
Meanwhile, the families of the two doctors are in mourning.
Dr. Field was an anesthesiologist at Beverly, Mass. -based North Shore Pain Management, while Dr. Bolanos was a pediatric anesthesiologist at Boston-based Massachusetts Eye and Ear and and an instructor at Harvard Medical School. It could not be determined if he has a lawyer.
After cops tracked Teixeira, he allegedly opened fire on the officers.
During Teixeira's arraignment in his room at Tufts Medical Center, Pappas offered a few details about the slayings.
Bolanos, 38, specialized in pediatric patients at Massachusetts Eye and Ear.
On its website, North Shore Pain Management said Dr Field was "instrumental in the creation of this practice".
It was that text that alerted officers to go to the building in a neighbourhood near downtown Boston that has been gentrifying.
Teixeira, 30, of Chelsea, had recently been released from jail after serving time for larceny. It was unclear whether he had obtained an attorney.
Teixeira received three gunshot wounds after police confronted him in the condo Friday night. No officers were injured.
"Teixeira pleaded guilty previous year to passing notes and demanding money from a downtown bank on two occasions".
