CBS 11 first met Perez and Hague in July during a profile of her restaurant that helps the homeless. Even since she opened, she’s been welcoming them inside to grab a cold drink, a snack and air conditioning.

Perez is not sure if Hague will survive the evening. Knowing someone punched and kicked her friend in the head brings tears to her eyes.

“You are three times the size of this guy. He’s homeless. A lot of the homeless have mental issues… you don’t know what they’re fighting… why did you have to hit him like that? There was no reason to do this to him. It was just words,” said Perez.
