FBI investigators searched a landfill for a safe allegedly belonging to the former stepfather of a 12-year-old Vermont girl whose body was found last week.

Investigators think the safe contains child pornography belonging to Raymond Gagnon, who was married to the mother of Brooke Bennett. Brooke vanished June 25. Her body was found buried in Randolph, Vt. after a weeklong search.

Gagnon, 40, faces obstruction of justice charges in the girl's disappearance and Michael Jacques, Brooke's uncle, has been charged with her kidnapping.

Erik Vasys, an FBI spokesman, said investigators have searched for the safe over the last week.

"The focus of our assistance is the recovery of hard drives related to the investigation," Vasys said.

Gagnon rented a room in San Antonio from Kevin Grosenheider, who according to an affidavit told authorities he threw the safe into an apartment complex Dumpster near his home at Gagnon's request.

Grosenheider is quoted in an affidavit as saying he didn't know what was in the safe "but assumed it was child pornography." Grosenheider said he only told authorities that he assumed the safe's contents were something Gagnon didn't want discovered.

An affidavit in federal court in Vermont says Gagnon acknowledged keeping child pornography in his safe.

Gagnon married Brooke's mother in 2000, but they later divorced.
