Surveillance video of the assault sparked outrage from the community.

The vicious attack left Erin McCarthy, 18, bruised and wondering why it happened, but she’s relieved someone has been charged with the crime.

Jordan Lamonde, 22, of Portsmouth, is accused of hitting McCarthy 39 times as she was leaving work at the gym and walking to her car.

McCarthy said she doesn't know Lamonde, but knows someone who does.

“I just am really glad that they caught him,” she said. “It was a messed-up situation in the first place. His reasoning was not valid at all.”

The investigation lasted about a month.

“We had felt that this case was targeted towards this victim, so we didn't feel that the public was in any danger,” said Capt. Jason Thomas, of Rochester police.

A tip led police to Lamonde. By the time they got the search warrant results, Lamonde was in the hospital. It's not clear why.

On Monday, Lamonde was medically cleared to leave. Officers were waiting for him.

“The Rochester Police Department has never had any contact with him prior to this incident,” Thomas said.

McCarthy said Planet Fitness offered her other shifts, but she decided to quit.

She said she feels OK physically and emotionally.

“I'm not, like, bad at all,” she said. “Nothing's really messed with me that much.”

Lamonde is being held on $150,000 cash bail. He is set to face a judge Tuesday morning and is charged with second-degree assault.
