Jessica Del Rocco, the high school girlfriend of Raymond Clark III the man arrested in the killing of Annie Le GRD ’13, said that Clark was controlling and “physical” with her that she notified the police when she was breaking up with him.

Del Rocco, who dated Clark when she was 16, gave an interview with Diane Sawyer this morning on “Good Morning America.”

She said he was an ideal boyfriend at the beginning.

“At first he was perfect,” she said. “He was charming, he was sweet, he took me out.”

About three months into their relationship he became “controlling,” she said, telling her what to do such as how to speak, where to go and what to wear.

As the relationship went on Del Rocco said she began to see Clark’s temper and anger more frequently.

“If things didn’t go his way then he’d make them go his way,” she said.

When Del Rocco told Clark she wanted to break up with him, she said he resisted and “an incident occurred.” She declined to comment further. After their relationship had ended, she had a police escort take her from her school to her car for about two weeks, she said.
