The convicted child rapist and Upper West Side building superintendent accused of soliciting sex from female tenants no longer has access to keys to dozens of apartments. According to the Post, landlord Stanley Katz is "evaluating what he's going to do" about Level 3 sex offender Williams Barnason, who is the super at three buildings on West 73rd and West 75th streets. For now, the super "has no access to the keys." Barnason served 14 years in prison after pleading guilty to raping, sodomizing and sexually abusing girls as young as five years old. Some tenants allege that Barnason offered to pay their rent and deposits if they would have sex with him. A Manhattan lawmaker has proposed legislation that would bar high-risk sex offenders from working as supers.
