Sex offender has not registered with officers as required since 2012

SAN ANTONIO - A convicted sex offender who is required to verify his information -- including his address -- with law enforcement officials every three months for the rest of his life hasn't done so since 2012, which has led to a new felony charge against him.

William James Mahoney, 52, was sentenced in 1999 to five years in prison for five charges of indecency with a 4-year-old girl by contact. Upon his release, he was required to register quarterly as a sex offender. The state's sex offender registry site shows Mahoney reported to the San Antonio Police Department in November 2012. It does not show he has reported to them since then.

"A warrant was issued for Mahoney's arrest following an indictment filed with the Bexar County District Court. The indictment alleged that Mahoney failed to comply with sex offender registration conditions and absconded from supervision," Deputy U.S. Marshal Chris Bozeman said.

Mahoney has gray hair and blue eyes. He is 5 feet 8 inches tall and weighs 176 pounds.

"His last known place of residence was on the South Side of San Antonio," Bozeman said.
