The Chicago Police Department says a heart attack was the cause of death for a 25-year verteran who collapsed while working in the River West area and died.
"On behalf of the entire Department, I offer my sincere condolences to Officer Ross' family, friends and colleagues" said Police Superintendent Garry McCarthy. "We will keep them in our thoughts and prayers during this difficult time."
Officer Preston Ross, 48, was in full uniform, working near the CTA Blue Line station at Grand and Milwaukee avenues Saturday morning when he experienced problems breathing, then collapsed, police News Affairs Officer Robert Perez said.
Ross was taken to Northwestern Memorial Hospital, where he was pronounced dead at about 10 a.m., Perez said. A spokesman for the Cook County Medical Examiner’s office said the office was notified of the death of an officer Saturday morning.
Ross was assigned to the 22nd District and had earned 17 awards during his career.
