Justice Dept. Investigating Commerce City PD Misconduct

Updated 1 p.m. -- The troubled Commerce City Police Department is opening itself to scrutiny from the feds in a voluntary move that comes after a string of high profile misconduct cases.

Officials announced plans for the voluntary review by the federal agency's Office of Community Oriented Policing Services on Wednesday. Standing next to Department of Justice officials, the city's police Chief Lowell Richardson called it a "monumental day."

The Justice Department frequently agrees to such reviews. This is believed to be the first time any police department in the Rocky Mountain region has asked for this type of review.
