After Steve Piskor installed hidden cameras in his mom's room at her nursing home back in 2011, he couldn't believe his eyes when he watched the tape.

"It's just really hard to look at," he said.

In one of the videos, the aid grabs Esther Piskor and throws her onto the bed causing her to hit her legs on the wall.

Another video shows her caregiver, Virgen Caraballo, grabbing Esther by her neck, screaming at her, throwing her into her wheelchair and then hitting her in the face.

"When I finally got to the point where I see her actually hit her, then I immediately stopped and took it to the police," said Piskor.

Caraballo, the former The Elisabeth Severance Prentiss Center employee, was sentenced to 10 and a half years behind bars, but after serving only six, she has a chance at an early release.

"Right now we don't feel like she entitled to any special treatment of early release," he said.

Piskor started an online petition to stop her from getting out early.

He said its the least he can do to honor his mother's memory. She passed away six months ago.

He's still waiting on the call from the prosecutor's office for the final word on the date of Caraballo's court hearing.
