Indiana house
An home that has long been reported to be a hotbed of demonic activity according to visitors has been demolished.

The residence, in Gary, Indiana, was destroyed two weeks by Zak Bagans, a host and producer of the show Ghost Adventures.

It was filmed for a documentary he plans to release later this year.

Bagans bought the home back in 2014 for $35,000 after Latoya Ammons reported that she and her three children had been possessed by demons while living there, a claim which was later backed up by members of the local police department and workers from the Indiana Department of Child Services.

'Something was inside that house that had the ability to do things that I have never seen before — things that others carrying the highest forms of credibility couldn't explain either,' Bagans told the IndyStar.

'There was something there that was very dark yet highly intelligent and powerful.'

The possession and exorcism of Ammons was actually filmed inside the house by police.

Throughout the hour-long film officers hear testimony of children picked up and flung against walls and furniture; of adults being 'choked to death' by some supernatural force; of a demonic form appearing in different shapes - the shadow of a man, a black looming monster; an apparition of a withered old lady with red eyes and hood; of a house that bled clear, odorless oil and of the household's three children convulsing and chanting Satanic verses.

In a chilling aside, in a separate audio recording made by one of the officers as he took pictures while his colleague filmed - audible here exclusively at MailOnline - the two officers' speech is cut across by a whispered, but clear, 'Hey.' Neither said or heard it at the time.

Both are now convinced it is a demonic rasp, issuing a welcome or a challenge as they stood unwittingly on the lip of a 'portal to hell.'

At one point, Ammons' mother, Rosa Campbell, who acted as 'paranormal tour guide' to the officers drawn from Gary, Lake County and Hammond Police Departments, admitted saying to her daughter: 'Nobody's going to believe this, Toya.'

Certainly few involved in the case wanted to when it began in early spring 2012. But today, the veteran police officers, experienced physicians, paramedics, nurses, social workers and clergy linked to the case speak of being 'attacked' by demons, profoundly shaken and left with little choice but to believe that 'something' possessed the 32-year-old mother-of-three and the rented home in which she, her children and her mother, lived from November 2011 until May 2012.

Rosa recalled an occasion on which she was down there alone doing some cleaning: 'I started coughing and joking so bad...I was praying the whole time and they don't like for us to pray. They don't like that at all.

'Something down there was choking me to death, I don't know what it is.'

On another occasion she said that her daughter, Latoya and godson were in the basement when, according to Rosa: 'He felt like something was stabbing him in the stomach. The more he was was reading the Bible, the more it was stabbing, punching... they saw something flying across the room and land "blam" like that.'

Rosa reached for the object she claimed had been flung by some demonic force - a small Holy Family ornament.

She also said that her daughter had told her that, as the force had grown in power she had seen it's full manifestation in her bedroom one night. 'She said it was like a scary, ugly, black monster... she couldn't say anything else.'

Two of them most disturbing physical manifestations were witnessed by several medics and law enforcement officials.

The first, Rosa recalled, was during a visit to family physician Dr Geoffrey Onyekum on 19 April 2012. Both focused on the youngest child, then 7. She recalled: 'I saw "it" trying to come out [of him]. It was trying to break loose in front of the doctor.

'His head was turning, his eyes rolled back, his mouth went crazy, he started talking in tongues then it threw my grandson completely across the room.'

The nurse who witnessed this would not go back into the room while the doctor, realizing this was well beyond his capabilities, called police and paramedics to take the child and his brother, both of whom fell unconscious, to Gary ER.

When there, and in the grips of demonic possession, his grandmother maintained, her youngest grandson - growling and gurning - walked backwards towards a wall then glided up it, walking backwards to above her head height, holding her hands all the way as she tried to coax him down and 'it' out, before flipping over her head and landing on the floor.

The child had no recollection of the event that was witnessed by nurses, social workers and paramedics all of whom recorded it in official reports.

Gary Indiana Police Captain Charles Austin, 62, was there the day the footage seen here was recorded. He entered a skeptic and left convinced that he had just witnessed a 'portal to hell.'
