(KMOV.com) -- Prosecutors say four Treasure's Office employees were pocketing parking fees at two city-owned lots near Scottrade Center.
When St. Louis Treasurer Tishaura Jones took office in January, she learned something wasn't right at two city-owned parking lots on Clark Street and 16th Street in downtown St. Louis.
"Our systems notice how many cars pass over a loop, the sensors in the ground, and that wasn't adding up,” Jones said.
Jones asked police to investigate.
William Draper, Blake Noise, Charles Roberson and Princeton White were charged with multiple charges of felony theft on Friday.
Prosecutors say the men were hired to collect $20 parking fees on several nights throughout March and April.
Instead of turning in all the cash, prosecutors say each suspect pocketed more than $500 on several different occasions.
According to court documents, at least two of the suspects admitted to pocketing money. Police said the crimes were all caught on camera.
"Do we think this practice was going on well before you got into office?” said News 4's Lauren Trager.
“We think so,” said Jones.
Jones said there is no way to determine how much money was stolen.
“Any message then, you want to send to any other city employee who might be engaged in this practice?” Trager asked.
“We are paying attention, so don't think we are not paying attention, because we are,” Jones said.
If convicted, the four suspects could face up to seven years in prison for each count of stealing.
