SYCAMORE – Bond was set at $15,000 Thursday for a woman who police say tried to conceal evidence from the scene of a gang-related beating in February 2010.

Karissa T. Marsh, 20, of the 1300 block of Sunrise Drive in DeKalb, was charged with concealing evidence after she retrieved a handgun from the crime scene and hid it in her car before fleeing the area in “furtherance of gang-related activity,” according to court documents.

Court files say Marsh attempted to obstruct the prosecution of Corey Frazier of DeKalb, who pleaded guilty in June 2010 to aggravated battery and was sentenced to two years in prison and $5,600 in restitution.
