Captured: U.S. Marshals need help to track down Alfonso Balboa; believed to be hiding in Milwaukee

MILWAUKEE -- A FOX6 viewer tip leads to arrest.

U.S. Marshals said 43-year-old Alfonso Balboa had been hiding out in Milwaukee for several years since breaking the rules of his parole. In that time, agents say he committed another crime, sexually assaulting a sleeping person in a residence on the city's south side.

"I believe that he is still being assisted by family and friends in South Milwaukee area,” agents say.

43-year-old Alfonso Balboa was featured on FOX6's Most Wanted in February. Now in May, authorities are still determined to track down his location. Balboa also goes by the nickname, "Curly."

Agents say Balboa has been able to lay low with the help of an extensive network of family and friends. Agents say they have made contact with relatives and associates on several occasions but apparently no one close to the convicted felon is willing to give him up. That's why authorities are hoping someone recognizes him and calls in an anonymous tip.

Balboa is described as being 5'11" tall and weighing 230 lbs.

If you have any information on his whereabouts you're asked to call U.S. Marshals at 414-297-3707.
