Officials tell News10NBC they will return to Lake Road on Tuesday to continue their investigation and to make sure there were no other victims.
At first sign of daylight, investigators will search through the seven houses burned down by a fire in Webster on Monday.
Four firefighters were shot, two of them were killed, while responding to that fire that police say was set up as a trap.
Investigators say the suspect, 62-year-old William Spengler, was found dead at the scene from a self-inflicted gunshot wound.
Police say Spengler's sister is unaccounted for at this time.
