LAWRENCE, Kan. (AP) — A 34-year-old man has been convicted in the death of a Lawrence man who was found bleeding outside a fast-food restaurant.

The Lawrence Journal-World reports that Joshaua Back was found guilty Friday of intentional second-degree murder in the May 2015 killing of Tracy Dean Lautenschlager. The jury also found Back guilty of felony theft.

Authorities say Back stabbed Lautenschlager in the neck outside a Lawrence home. Lautenschlager was found bleeding in a McDonald’s parking lot. He was pronounced dead at a hospital.

Back fled in a truck that he told authorities he planned to steal as collateral for a drug debt. He was arrested two days later in Leavenworth County. The defense said the killing was an act of self-defense.

Sentencing is scheduled for June 2.
