PHOENIX (AP) -- The U.S. Marshals Service says a Michigan sex offender who made the state's "Top Ten Most Wanted" list has been arrested in Arizona. Authorities say 51-year-old Anthony Wayne Dolson pleaded guilty in 1993 to several counts of sexual contact with someone under the age of 13. They say he failed to register as a sex offender and fled. The U.S. Marshals Service in Arizona was able to track down Dolson and arrest him without incident Thursday morning. It's unclear if Dolson has an attorney.
