Daisy Villalobes and Tiffany Mulgado saw the couple getting into it when they were walking back from lunch.

“It was scary,” said Villalobes, “the girl was screaming, he was hitting her. Everything was just happening so fast.”

“He was a big guy,” said Mulgado, “she was pretty slim.  I mean, there’s only so much she could do to fight him.”

The two didn’t feel that it was safe for them to intervene but they were one of many to call 911.

The two women were glad to hear it wasn’t an actual stranger abduction.

Mulgado says she was still shaken up by what she saw.

“She was scared for sure,” Mulgado says, “She was scared It’s just sad. Hopefully, she’s okay.”
