A Stamford woman thanks a New York police officer and exorcist who she claims helped chase a demonic possession from her house.

Glenda Bosanko says when she first found the modern home on Guinea Road, she thought she was looking at her dream house. But it wasn't too long before things became a nightmare.

"I heard something every day. I heard something fall, I heard something crash - yeah. Growling," she says.

Bosanko says it was one night in April when the crashing, footsteps and banging reached their peak.

"I actually thought maybe it was an intruder, and I was here in the house alone. So in case I was going to be murdered I wanted some evidence, so I brought my phone."

Chris DeFlorio has been a New York City police officer for 18 years. In his spare time, he's a self-trained religious demonologist.

"It's basically the study of demons and the occult through a biblical worldview. That has always been my worldview," DeFlorio says.

DeFlorio and wife harmony say their non-profit Office of Demonic Investigations grew out of their New York City homeless ministry, Seek and Save outreach.

After a few visits, the DeFlorios decided to attempt an exorcism. Deflorio says as soon as he started the ritual, the air started to stink, and a banging sound filled the attic.

It took a few more visits and a few more blessings before the Deflorios declared their work on the house finished.

Bosanto says it was like night and day from when she was scared to leave her bedroom.

"After they left, the energy changed. It was like, I could come and sit in my living room."

So, does Glenda really believe her house was possessed by the paranormal?

"100% real. And I would have been a person that questioned it before."

Whether you're a believer or a skeptic, DeFlorio says there's no greater calling than giving the gift of peace of mind.
