UPDATE: Boston Police identify the suspect as Bampumim Teixeira, 30, of Chelsea; say the victims were a man and a woman in their 50s.
Around 8:40 p.m. in an 11th-floor penthouse unit at the Macallen Building at 141 Dorchester Ave. Cheryl Fiandaca at WBZ reports they were bound and had their throats slashed.
Police and residents say officers arriving on scene to investigate a disturbance found themselves shot at by a man in the unit; they returned fire, hitting him several times. He was then rushed to the hospital.
Police ordered residents in both the MacAllen and a neighboring building to shelter in place as they conducted a floor-by-floor search. Broadway and West 4 Street were shut.
At 10:10 p.m., police lifted the order for the neighboring building, but kept the Macallen locked down. Not long after, Broadway and West 4 were re-opened to traffic.
The unit in which the two victims were found is a 2,000-square foot condo valued at $2.1 million, according to city records.
This is the second violent incident at a Boston luxury condo this year. In February, a man was stabbed at the Residences at the W Boston on Stuart Street.
