A 30-year-old man kidnapped, raped and tortured his wife, then hung her from a tree to film a two-hour bondage pornography video, authorities said Tuesday.

The man was charged with aggravated assault and battery, sexual battery, kidnapping, and false imprisonment. He was being held in the Brevard County jail on Tuesday in lieu of $3 million bail.

"I don't know how to even explain it," sheriff's deputy Marlon Buggs said, adding, "the victim will be mentally scarred. He humiliated her."

The Associated Press does not identify victims of sexual assault. The man was not identified in an effort to protect his wife's identity.

The couple went on a canoe trip down a canal on Saturday and pulled ashore near some trees, when he began raping her and taping it with a video camera, Buggs said. He tied her to a tree, where she hung naked for several hours, her toes grazing the ground.

He struck her with the side of a hunting knife blade, leaving bruises, then raped her again, Buggs said.

It appeared the man was following a computer printout describing the crime in detail that was found at the scene, Buggs said.

If convicted, the man faces a life sentence, Buggs said. He will appear in court Feb. 9. His attorney's name was not immediately known.
