“She said, ‘I’ll get the ladies involved, you got a problem, bitch’ and starts punching me in the head,” Long said. “I put my hands in front of my face. She had me against the brick wall of the Delphic. I’m crying uncontrollably. She’s pummeling me.”

When the Harvard University Police Department arrived, DeFrancesco said, the suspects had fled in the car and the police were left with little evidence to determine their whereabouts.

“When they got there everyone was gone,” DeFrancesco said. “There was no [license] plate number, nothing.”

No one has been arrested and there are no suspects at this time, DeFrancesco said yesterday.

Long said the suspects appeared to be 26 years old.

Long said her injuries included bumps and bruises all along the back of her head. Pearson said, in addition to suffering from bruises, he had to have an emergency root canal Sunday.
