According to prosecutors, a friend of the couple called police and said he got a text message from Field, which was described as “a plea for help.”
The text message said there was a gunman in the apartment, which prosecutors say was detailed in a recorded 911 call from the friend.
Officers who showed up at the condo found a set of keys on the floor in front of the door. Police said they knocked and announced their presence.
When no one answered, officers said they used the keys found on the floor to enter the apartment, which was dark.
Officers conducting a sweep of the apartment found a man, who started to shoot at them. Police said they shot back and hit the man in the leg, abdomen and hand.
Teixeira was arrested at the scene, treated for his wounds and then taken to Tufts Medical Center, according to police.
The Boston police team went into the apartment and found Bolanos and Field bound, “having sustained obvious trauma.” They were both pronounced dead at the scene.
A black backpack was found in a "remarkably conspicuous location." It was filled with jewelry belonging to Bolanos, according to police.
