When authorities arrived on the scene, they found the home in a state of disrepair with clutter inside the house.
Members of the Emergency Services Unit and Crime Scene Unit used protective gear and respirators to search the house.
They eventually found skeletal remains in a bedroom.
For years, neighbors complained about the horrific smell coming from the house. They knew there was trash and feces piled feet high, but no one who lives here had any idea a body was inside, possibly for years.
"Of course it freaks you out. She's a sick lady. What are you gonna do?" said Louis Longo.
Swenson is known in this community to be a hoarder. She lived here with her elderly father, who neighbors haven't seen for years.
"We've been here for 4 and a half years. I've never seen her father," one neighbor said.
She apparently told some people that he was in a nursing home.
Neighbors say the smell and the trash was bad enough, but they say the big problem they had raccoons and rats would constantly be going in and out of the house.
The Westchester County Medical Examiner will examine the remains to determine cause of death and how long the body may have been inside the house.
Whatever the case may be, everyone here feels sorry for Swenson. Hoarding is a sickness, but they are relieved that finally the house will be cleaned up.
