Police in Springfield say there was some kind of "transaction" that went bad on the northside Walmart Supercenter parking lot Monday morning.
There was a large pool of blood where a man was stabbed, but there was no victim or suspect there when officers arrived on scene.
A 9-1-1 call said a man was cleaning blood off his truck on Bolivar Road, which is near the Walmart.
Another call to police was from a local hospital saying a man showed up to be treated for stab wounds in his chest. The man will survive.
Investigators say all of these incidents are related, but no one is cooperating.
