TOPEKA, Kan. (AP) — A homeless woman previously convicted of murdering a homeless advocate has pleaded guilty to lesser charges.

The Shawnee County District Attorney announced Tuesday that Kimberly Sharp will be sentenced Sept. 30 for voluntary manslaughter and aggravated battery in the death of 38-year-old David Owen, a homeless advocate from Topeka who disappeared in June 2006. His body was found the next month.

An appeals court in July ordered a new trial for Sharp, ruling that her confession was involuntary and should not have been admitted at her first trial. The court said the confession couldn’t be used in a new trial.

Owen was killed during a confrontation at a homeless camp near Topeka.

Two men also were convicted of first-degree murder in Owen’s death. Another person was convicted of involuntary manslaughter.
