(AP) — Divers who searched a lake found no evidence in the death of a Topeka developer.

The  underwater search of Lake Shawnee was tied to the investigation into 39-year-old Corey M. Brown’s death. But Topeka police said Tuesday that divers from Douglas County only found junk. Police aren’t discussing what authorities were seeking.

Forty-year-old Monroe Eugene Lockhart III 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. Lockhart already was serving a nearly 10-year sentence for a home invasion when he was charged in Brown’s death.

Bond in the murder case has been set at $1 million. Lockhart’s attorney isn’t commenting.
