I live in a group home for the mentally ill in MD. And my roommate has a registered sex offender visit her. There is a Young girl next door. What should I do?

Do you know if there are any restrictions put on the person as far as not being able to visit the group home? You can make a staff member aware of your roommate's visitor's record and they can look into from there. If that staff member doesn't know exactly, they would know who does and could let that person know.
