Officer Haggerty was electrocuted by a downed power line.

Officer Michael Haggerty and Officer Tom Klecka were on foot patrol near Grand Boulevard and Wyoming Street during a storm when they noticed a broken power line hanging close to the ground. The 2300-volt Union Power and Light line end of the wire was hanging several feet above the ground. The officers notified the station of the wire and were directing traffic around it.
