DA: 3 Found Dead In Waltham Apartment

Authorities say the killing of three men found dead in a Waltham apartment was not a random act and the victims knew their assailants.

The Middlesex district attorney's office says investigators are searching for two suspects who were in the apartment at the time of the slayings on Monday afternoon.

Neither the names of the victims not the names of the suspects were immediately released. The manner of death was also not disclosed. Autopsies are scheduled.

Neighbors say the residents of the house rented in the largely residential neighborhood around Harding Avenue.

Police say there had been two other slayings in the city within the past year.
