COLLINSVILLE • A Collinsville police officer who sought felony drug charges against his neighbor in November has now been criminally charged with four counts of obstruction of justice stemming from the incident.

A Madison County grand jury indicted Officer Luke Tillman, 34, Thursday for his actions during a Nov. 16, 2011 traffic stop made just outside the Collinsville city limits.

Tillman pulled over Cheryl Helfrich, 50, of Maryville for failure to display any registration and claimed to find a "crack pipe" inside Helfrich's car. He arrested the woman and the Madison County State's Attorney's Office charged her with unlawful possession of a controlled substance on Jan. 18.

Then, in March, the woman's attorney told the state's attorney that Helfrich did have temporary registration affixed to her car at the time of the stop and asked whether a video or audio recording was made of the incident as it wasn't mentioned in Tillman's report, according to a press release from the Madison County State's Attorney's Office.

Per procedure, the Collinsville police department requires in-car videos to be logged if the end result is a felony charge.
