Dupo police responded about 5 p.m. Sunday to a report of possible shots fired and a man loading a firearm in the area of Good Times Saloon at the corner of North Main Street and Emma Avenue.

Area law enforcement agencies were put on the lookout for a gray Kia sedan car with a suspect described as a white man wearing a black shirt and a red, white and blue bandana. Another vehicle involved in the incident was a maroon Nissan sedan.

A Cahokia police officer stopped the gray Kia in the 700 block of North Main Street in Dupo a short time after the incident and recovered a loaded .45 caliber Springfield Armory handgun in the back seat as well as approximately six grams of methamphetamine, 15 buttons of heroin and two ounces of weed in the car.

Dupo police said two occupants of the maroon Nissan told officers that although no shots were actually fired, the man in the Kia threatened to shoot up their car if they did not pay $1,600 as part of a drug deal. The incident allegedly began in Missouri, police added.

Dupo police left the Nissan temporarily to verify the victim’s account with the man pulled over in the Kia with the firearm. When the officer returned to the site of the Nissan, that car and its occupants had left and turned off their mobile phones so as not to be contacted.

The incident remains under investigation.
