Two people were charged with unlawful use of a weapon after police were called Tuesday to a residence in the 1300 block of Richard in unincorporated St. Clair County near Cahokia to investigate a possible crime.

Saavion Scott, 20, of Cahokia, was charged with two counts of aggravated unlawful use of a weapon. Bail for him was set at $15,000. Verneda L. Scott 36, of Cahokia, was charged with one count of unlawful use of a weapon. Her bail was set at $10,000.

Police believe Verneda Scott is the younger Scott's aunt.

St. Clair County Sheriff's Lt.. Kurt Eversman said police were not sure whether a domestic disturbance or a break in occurred. He said when police arrived at 1319 Richard, they were told their services were not needed.

Feeling there was something suspicious going on at the home, police stayed in the area.

"A short time after police left the door, some people left the home and got into cars and drove away from the home at a high rate of speed. The officers got in behind the second car and attempted to stop it. No one was charged in the second car. Meanwhile, a passenger in the lead car opened the door and jumped from the vehicle," Eversman said.

"He ran with a backpack on and what looked like a shotgun in his hand, down an alley off of St. Michael Street," Eversman said.

Cahokia officers were called and joined in the pursuit of the suspect. Eversman said Saavion Scott was arrested in a back yard on St. Michael. Verneda Scott, another passenger in the first car, was charged with weapons violations after police searched the car and found a 9mm handgun and a AR-15 .223 assault rifle, Eversman said.

The third person in the vehicle was not charged.
