Police body cam footage shows arrest of man accused of beating a woman, setting her on fire

A Liberty Township woman was listed in critical condition Friday, a day after being beaten, set on fire and jumping out of a second-story window.

Her boyfriend's son, Robbi Robinson Jr., 23, was arrested and charged with felonious assault and aggravated arson.

Footage from a Fairfield Township police officer's body camera shows an officer approaching Robinson at the scene on Arroyo Ridge Court. Robinson is wearing a winter coat with the hood pulled up.

"I don't know what happened," Robinson said to the officer.

When police asked if anybody else was inside the house, he said his "stepmother" was.

The officer replied, "Your stepmother jumped out the back."

Robinson said, "Oh, she did?"

He was placed in handcuffs, questioned and charged later that day.

Robinson is accused of beating the woman so badly at least two of her teeth were knocked out, according to court documents. Police said Robinson then set her on fire.

She ended up jumping out of a second-story window.

Dennis Williams, a neighbor, found her on the ground, covered in burns.

He called 911.

In the 911 call, you can hear Williams relay information from the victim to the dispatcher.

"Do you know if he had any weapons?" Williams asked the victim.

He then tells the dispatcher, "Water with gasoline. He threw it on her."

She was flown to the hospital. During Friday's arraignment, prosecutors said she was in a coma.

Robinson's bond was set at $200,000.

Police have not released information on a potential motive.
