(AP) — Divers are searching a northeast Kansas lake as part of the investigation into the 2012 shooting death of a developer.

Officers investigating the death of 39-year-old Corey Michael Brown retrieved several items by noon Monday from Lake Shawnee. The  retrieved items included lawn chairs, fishing poles, old bottles and cans.

Forty-year-old Monroe E. Lockhart is charged with first-degree murder in the death of his friend and business partner. Lockhart also faces a felony arson charge in Shawnee County District Court.

Lockhart is already incarcerated for other crimes. Earlier this year, he was sentenced to serve nearly 10 years in prison in connection with a November 2011 home invasion.

The dive team comes from Douglas County. It was requested by the Topeka Police Department.
