Topeka ? The Kansas Supreme Court upheld the murder conviction of Kimberly Danielle Sharp, one of four people convicted in the death of a lobbyist for the homeless three years ago.

The court ruled Friday that Sharp’s conviction of life without parole for 20 years was proper. It said the evidence could show she participated in a conspiracy to kill lobbyist David Owen.

Owen disappeared in June 2006. His body was found the next month in a wooded area near the Kansas River.

Prosecutors said the four defendants became upset with Owen because he wouldn’t leave the homeless camp, so they tied him to a tree, where he eventually suffocated. Owen was known for giving homeless people telephone calling cards and urging them to call home. His detractors said he was often pushy.
