Investigators did not know the motive and had no suspects, Elsworth said. Investigators identified the victims as Phuong Hung Le, 30, his wife, Trish Dawn Lam, 25, and Lam’s 6-year-old son, Tommy. Their bodies were found in separate rooms upstairs. Tommy was killed in his bedroom, police said. The baby girl, whose name was not released, spent as many as three days alone with the bodies before being discovered by police Monday evening. Because of the 1-year-old’s dehydrated state, detectives believe the killings may have occurred Friday night – the last time the family was heard from. The baby girl was taken to a hospital for treatment and placed in protective custody. Authorities said there were no signs of forced entry, suggesting the couple might have known their attacker. Le had a criminal history, but police said they were not sure whether that had any bearing on the case. State prison records showed a Phong Hung Le, 30, was sentenced to four years on a robbery conviction and more than two years for destruction of jail property. The couple, who had been dating for several years, married in 2005, according to Trish Lam’s brother.

Neighbors passed by, and the Memorial Day weekend drew to a close. All the while, the walls of the tidy, two-story house kept secret the bloody scene inside. It was only when police conducted a welfare check that they uncovered what had happened to the residents – a baby beaten, dehydrated and crawling around in a soiled diaper and her parents and brother dead upstairs. “It’s one of the most horrific crimes that we have investigated in many years,” Lt. Dennis Elsworth said Wednesday.
