Dane County prosecutors have charged four men with repeatedly raping a 16-year-old girl last January.  The most serious felony charges are filed against 25-year-old Sean Reason.  Originally, the girl told police she had consensual sex with 10 men as part of a gang initiation.  Later, she told a Sun Prairie police officer and two social workers she was gang-raped and didn’t want to have sex.  She had been missing for six days when she turned up January 27th.  Twenty-year-old Leshaun Cole, 18-year-old Semaj Pruitt and 21-year-old Kashawn Redus all face felony charges in the case.  Reason made a court appearance Friday.
