Police were awaiting autopsy results from the Delaware County Medical Examiner's Office Sunday to determine what caused the deaths of four people found in a home in Chester.

Authorities said there was no sign of forced entry at the home, and that they had ruled out carbon monoxide poisoning.

Chester Police Chief Floyd Lewis said police responded to the home around 7:30 p.m. Saturday after getting a call from a relative.

Once inside, police found the bodies of a man and two women and a toddler. All of the adults appeared to be in their 20s. Lewis says there was no sign of trauma on the victims, who were found in the living room and the bedroom.

Police said the deaths are suspicious.
