Mohawk-wearing Isabel Dawson charged back into the East 13th Street squat this week where she raised her daughter, Rosario Dawson, to change the locks on a unit where she lived two years ago. The squatter who now lives in the apart ment is livid, and other resi dents say they want Isabel gone because she bullies for space. A spy says she shouted at the tenants, “I’m not embar rassing my daughter! This is a squat, I can live here.” Isabel didn’t get back to us.
