UPDATED, AGAIN: They've located Stewart. No other information is being released, though the dead man has been identified: Stephen L. Cook of California.
UPDATED: Carlos has been found in KCMO, and is in good shape. Police still want to talk to Stewart.
PREVIOUSLY: Olathe police want to question a man in connection with a homicide yesterday at an Econolodge, and there's special concern because they think he's traveling with a 3-year-old boy.
The man's name is Maurice O. Stewart, 22, and he's described as a person of interest, not a suspect. The boy is Carlos Angel Villegas III, and he's been added to a national database of missing and endangered kids, though it doesn't appear he was kidnapped. The case doesn't meet the standards for an Amber Alert.
The homicide involved a 57-year-old man found Tuesday morning at the motel in the 200 block of East Fleming.
