Bethel, Vt. ? The body of a missing 12-year-old Vermont girl was found Wednesday buried near her uncle’s home, hours after documents surfaced that accused the man of planning to initiate her into a child sex ring.

Brooke Bennett’s body was found about 4:45 p.m., about a mile from her uncle’s house, said State Police Director Col. James Baker. Police who had been searching the uncle’s property noticed the ground was disturbed and found her body buried underneath.

The girl’s uncle, Michael Jacques, who has been in custody since Sunday on sexual assault charges involving another underage girl, is to be charged in federal court with kidnapping, police Sgt. Tara Thomas said.

Bennett was last seen alive with Jacques at a convenience store last Wednesday.

“The painful discovery of Brooke’s body today is tragic and heartbreaking,” Baker said.

He called the death “clearly suspicious” but declined to give details before a planned briefing Thursday morning.

On Wednesday night, about 300 people gathered to mourn Bennett’s death in what was originally organized as a candlelight vigil for the girl’s safe return.

“Brooke Marie, I love you so much,” her mother, Cassandra Gagnon, said sobbing. “I just ask that justice be done for the person who took my baby away.”

The girl’s father, James Bennett, added, “I know Brooke knows that we love her and will always love her.”

Earlier Wednesday, in an affidavit unsealed in U.S. District Court in Burlington, the FBI said an unidentified 14-year-old girl told investigators she was present on June 25 when Jacques, 42, tricked Bennett into thinking she was going to a party and took her to his Randolph home to be initiated into a sex ring.

The girl said she was led to believe that the 12-year-old “would have sex with adult males” during the initiation.

The teenager said she and Bennett watched television for a while before Jacques told her to leave and took his niece upstairs. The witness said she left the house and didn’t see Bennett again.

The 14-year-old said she herself had been having sex with Jacques since she was 9, as part of the sex ring.
