A somber Genesee County Sheriff Robert Pickell told reporters Monday that it appeared the family ‘dropped where they stood’. The bodies of 35-year-old Len and 39-year-old Heather Quasarano, and their children — Luke, 11, Brenden, 9, Rachel, 7, and Grant, 2 — were found by a relative Sunday afternoon in the Stony Brook condominium neighborhood.The Genesee County Sheriff’s Office believes carbon monoxide killed two adults and four children to die in their Fenton Township home. A running generator was found on the scene and is believed to be the likely culprit in the poisonous gas leak, Sheriff Robert Pickell said. “It’s very difficult just talking to the undersheriff who was in the house and saw all the bodies in the different rooms,” Pickell said. “No matter how long how many investigations we conduct, seeing young children, an entire family wiped out is just a very, very sad thing.” Pickell said the generator had been on since at least Friday when the area experienced a power outage. A grandfather started to worry when the “very loving Christian family who attends church regularly”” were not in the pews at church Sunday. Genesee County Undersheriff Chris Swanson described the scene as “horrific.”
