Man: Wife's death was sex fantasy accident

Arthur Sedille was up-front with police: He would often put a gun to his wife's head during fantasy sex play at their Oklahoma City, Oklahoma, home.

But Sedille said he didn't know the gun was loaded when he pressed it to his wife's head and pulled the handgun's slide back during sex on the night of December 21.

Now Sedille, 23, is facing the possibility of a murder charge in Canadian County, Oklahoma, in the death of his wife, 50-year-old Rebecca Sedille -- who died when the handgun went off in their bedroom.
