One convicted sex offender went missing when he removed his G-P-S monitoring device and that led to questions being asked.  Now, broadcast reports indicate there are 13 Wisconsin sex offenders which can’t be located.  Thirty-one-year-old Brandon King had just been released after serving time for sex crimes involving a child.  He either removed the G-P-S tracker or caused it to stop working.  There are active arrest warrants out in the names of the 13 missing offenders.
