Police department
In 1945, the village was patrolled by Charlack's first sheriff accompanied by two deputies. The Police Department now has eight full-time employees, a chief, a pair of sergeants and six patrolmen as well as five reserve officers. The department has approximately nine patrol vehicles ranging from 4-5 Dodge Chargers, a Ford Explorer, a Dodge Sprinter Van, and a Ford Escape Hybrid outfitted as a Mobile Radar Photo Enforcement Unit made by Redflex Systems and acquired in late 2011. It also has a Chevy van used to set up photo enforcement cameras. Dispatch is provided by St. Louis County. Charlack began using speed cameras in March 2010. The cameras are provided by B&W Sensors, a company located in St. Louis. The speed cameras are on a mobile trailer which is located on top of I-170 on the Lackland Road Overpass. Charlack's then-police chief, Tony Umbertino, claimed that traffic fines account for about 29% of Charlack's operating budget. According to the then- Police Chief Umbertino, "The cameras have also been used on Lackland Road and Midland Road earlier in the year." Umbertino also served as the town manager. Charlack has been criticized by the St. Louis Post-Dispatch for painting speed camera calibration lines on the highway without obtaining the proper permission. The Post-Dispatch has also reported that Charlack has complied with a previous agreement to man the speed camera stations. The department contracts with an outside vendor to collect traffic fines online. In March 2013, former police chief and city administrator Umbertino was charged with financial abuse of a senior. Press reports are unclear as to the outcome of the case. In October 2014, Umbertino was found guilty on corruption charges that he used government funds to pay for meals and a trip to Hawaii.
