The owner of the house used by the Sigma Pi fraternity to torture new Hofstra pledges with forced vomiting in a basement adorned with a swastika said Wednesday that she had no idea she was renting to such nasty boys — and that they caused $20,000 in damages.

“Never mind what they did to each other, you should see what they did to my house!” seethed Rosa Taveras, 58, who owns the Meadowbrook Road home in Hempstead, LI. “They totally destroyed the place. They set a fire in the back, they dumped garbage everywhere, they broke the sinks and destroyed the plumbing. They were aninmals.”

Photos taken during the 2014 or 2015 university pledge week show one student locked in a small dog cage and another young man blindfolded and grimacing as hot sauce is poured on him as he stands in front of a wall with a swastika on it.

The photos, published Tuesday by the Hofstra Chronicle, were taken in the basement of Taveras’ house, where some members of the fraternity lived while attending classes at the campus a half-mile away.

Taveras, 58, said she had no idea what was happening in the Cape Cod-style house she bought in 2003 as an investment property.

She said she leased the five-bedroom home through a rental agency to a man in his mid-30s for $3,900 a month who subleased the rooms to college students.

“They did terrible things,” she said. “I had no idea until I was able to kick them out.”

Hofstra officials had been investigating complaints of the extreme hazing, and the fraternity’s charter was revoked last spring.

“The university condemns the incidents depicted in the photos and reported in the story, and has commenced an immediate investigation,” the college said Wednesday.

The school also has contacted police to investigate “any potentially criminal behavior.”
