Two people have been arrested and charged in the killing of a Lawrence native found shot to death Wednesday in Kansas City.

Jackson County, Mo. Prosecutor Jim Kanatzar announced that Lamar D. Quarles, 18, and Antonio E. Smith, 17, have been charged with second-degree murder, robbery and armed criminal action in the death of Derek A. Orchard, 37, Overland Park.

Orchard, who grew up in Lawrence, was found early Wednesday morning in a parking lot of an athletic field at 107th Street and Skiles Avenue.

According to court documents, Quarles and Smith were in police custody before the killing was discovered. Kansas City police stopped a gold Honda Accord belonging to Orchard shortly after midnight Wednesday near 12th Street and Paseo Boulevard.

Police became suspicious when Quarles, Smith and two passengers in the vehicle gave conflicting accounts on how they obtained the vehicle. The occupants of the vehicle were taken into custody and questioned, and among the items found in their possession was a handgun and Orchard’s credit cards.

According to a detective’s report, Smith admitted to police in an interview that Orchard had approached him and Quarles at the Riverview Garden Apartments in the 1500 block of East Missouri Avenue and indicated he “wanted to party.” Smith told police Orchard then drove him, Smith and two other people to the park.

“Upon arriving at the park, the occupants exited the vehicle and Smith entered the driver’s seat,” Detective Alane Booth wrote in the report. “Quarles then pointed a gun at the victim and told him to put his hands in the air.”

Smith told police that Quarles then shot Orchard and went through his pockets before the group fled in his vehicle, according to the report.

Prosecutors have requested a $250,000 cash bond for each of the defendants.
