Police said Friday that officers are re-examining the Naomi Drive home as the operations changes into a murder probe. No one has been arrested and police say they are in the process of developing suspects.
The revelations come a day after police conducting a welfare check found three people - two women and a man - fatally wounded.
Officers went to the home after a relative was unable to contact its residents.
Police say the back door of the residence was unlocked. They call it an isolated incident.
Lt. Curtis Stoldt told The Hartford Courant that the deaths are not a random act and that there is no evidence that other people are in danger.
