A 49-year-old woman was given six-years to life in prison Monday for sexually assaulting a child in 2005.

Debora Schreffler, who learned her fate before a 4th Judicial District Judge, will also have to register as a sex offender for the remainder of her life, said District Attorney's spokeswoman Lee Richards.

Schreffler, also known as Debora Knox, was convicted of multiple counts of sex assault on a child in a position of trust in late August for her participation in the ongoing abuse of an 11-year-old, Richards said. Schreffler was arrested in Sept. 2011.

Richards said the assaults were brought to the attention of authorities in Dec. 2010 when Schreffler’s ex-husband Raymond Knox was already serving a possible life sentence in the state Department of Corrections for sex assault on a child. The couple was divorced in 2007.

According to the DA’s office, Schreffler, Knox and 65-year-old Robert Tysor all faced charges for sex assault on the same victim. Tysor was sentenced to 16-years to life in prison in March for his role in the abuse.
