SAN ANTONIO (AP) - A man was arrested Friday on a charge alleging he helped destroy evidence for the former stepfather of a 12-year-old Vermont girl who was abducted and killed.

The arrest of Kevin D. Grosenheider, 58, from San Antonio, was the latest development in the case of Brooke Bennett.

Authorities say Brooke was to be inducted into a child sex ring by her uncle on the day of her disappearance in June. Her body was found in a shallow grave days later.

Brooke's uncle has been charged in her death.

According to an affidavit obtained by the San Antonio Express-News, Brooke's 40-year-old former stepfather Raymond Gagnon called and asked Grosenheider to throw away a safe with evidence that implicated Gagnon and someone else in the sexual assault of a minor girl. Grosenheider was renting a room to Gagnon at the time.

The affidavit said Gagnon apparently called Grosenheider on June 30, the same day he was arrested in Vermont on an obstruction of justice charge during the investigation of Brooke's disappearance. The obstruction charge was dismissed, but Gagnon has been indicted in San Antonio on charges of producing and possessing child pornography.

The affidavit said Grosenheider initially lied to investigators about the phone call but later admitted Gagnon had called him. Grosenheider also told agents that Gagnon showed him images of child pornography on a cell phone and a home computer, according to the affidavit.

Grosenheider was charged with misprision of a felony - not reporting or helping cover up a crime.

He was released on $40,000 bond, and another hearing was set for Oct. 30. Grosenheider didn't have an attorney and told the court he would hire one, federal court clerk Aurora Cisneros told The Associated Press.

Brooke disappeared June 25 and was found dead a week later. Her disappearance triggered Vermont's first-ever Amber Alert.
