A woman from Kansas City pleaded guilty today for her part in the death of a woman whose sexual torture and suffocation she and her boyfriend videotaped.

Attorneys for Dena Riley (above), 42, reached a plea agreement with the state in the May 2006 death of Marsha Spicer (left), who was suffocated during sex at an Independence apartment that Riley shared with her boyfriend, Richard Davis.

Riley also pleaded guilty to several charges related to the death of 36 year-old Michelle Huff-Ricci's remains were found in nearby Clay County, where Riley and Davis, are charged with capital murder.

Riley was sentenced to life without parole on the murder charge. She received eight life sentences on the other charges.

Riley and Davis' (left) crimes came to light after the couple kidnapped a little girl who was related to Davis in Kansas. Riley pleaded guilty to the federal kidnapping charge today too. Court documents indicate that the 5 year-old had injuries consistent with sexual abuse.

Davis was convicted and sentenced to death earlier this year for Spicer's slaying.
