Two days into the investigation of three suspicious deaths at 12 Harding Ave., here is the latest information from Patch and other local media outlets. 

• Victims: A next-door neighbor of 12 Harding Ave., Meredith Langton, told the Boston Globe the victims are in their mid-20s. Middlesex District Attorney spokeswoman Cara O’Brien told Patch the Office of the Chief Medical Examiner had not yet positively identified the victims, but hoped to do so today. Typically, the DA does not reveal the identities of victims until they have been positively identified and the next of kin has been notified.

• Possible Suspects: The Globe also reported that police are actively searching for two people who had been in the building before the deaths. WCVB-TV reported that the police were searching for two men. O’Brien told Patch said she could not comment on whether police were searching for suspects. Waltham Police Department spokesman Sgt. Timothy King told Patch he could not comment on that either.

• Discovery Of Bodies: Langton, the neightbor, told the Globe that she saw the girlfriend of one of the victims exit the home after finding the three bodies. The girl, Langton told the Globe, was distraught and said the bodies were covered in blood and marijuana.

• Cause of Death: According to WCVB-TV, the victims were stabbed with a knife or ice pick. O’Brien told Patch an autopsy would determine the causes of death.
