CAHOKIA — Thanks to the keen nose of the Police Department's canine, four adults and a juvenile are in jail accused of robbing an Imo's Pizza driver.

On Saturday, police said the four adults were charged with aggravated robbery. They are: Vortex L. Bolden, 18, of 38 Westwood Drive; Keombra A. James, 18, of 47 Westwood Drive; Linda G. Thomas, 17, of 52 Drexel Drive; and Jessica L. Williams, 22, of 1414 Richard Drive. Bail was set at $50,000 for each suspect.

The driver was robbed while delivering a pizza to a home on Westwood Drive on Thursday.

"When he arrived at the residence there, he was met by two female subjects," Police Chief James Jones said. "They began discussing the transaction with the driver. Two male subjects came from the side of the house. They inferred that they had a gun, but it was not displayed."

The suspects took an undisclosed amount of money along with the pizzas, Jones said. The pizza delivery driver, who was not injured, called police. A canine responded with the officers and tracked the suspects' scents to another residence on Westwood Drive, Jones said.

"If it were not for our canine, we might not have located these suspects so quickly. We are very thankful to have these individuals in custody," Jones said.

The driver, whose name was not released, was working out of the Imo's Pizza at 1282 Camp Jackson Road.

The four adult suspects will be held in the Cahokia jail until Monday when they are scheduled to be arraigned. The juvenile was being held in the St. Clair County Juvenile Detention Center and more information about his case may be available on Monday, police said.
