Businesses around Cleveland (OH) have collectively decided to illuminate their buildings in blue light in memorial to Detective James Skernivitz, who was killed in the line of duty last week while working undercover.

According to Fox News, the Terminal Tower in downtown Cleveland will light up blue through Sunday, and nearby buildings will light their exteriors in blue during that time as well.

A 15-year-old suspect allegedly shot and killed Detective Skernivitz and a police informant—identified as Scott Dingess—as they sat in a parked car last week.

The suspected gunman—whose name has not been released because he is a minor—now faces five charges of aggravated murder, two counts of murder, two counts of aggravated robbery, and two counts of felony assault.
