Authorities have released the name of a man who died shortly after police found him running in and out of traffic on an Irondale roadway.

The Jefferson County Coroner’s Office identified the man as Phillip David Reeder. He was 52 and lived in Vincent.

Irondale police officers were dispatched at 5:10 a.m. Tuesday on several 911 calls reporting the man’s behavior on Highway 78 near Old Leeds Road.

Lt. Jason Hill said the officers found Reeder who appeared to be under the influence of an unknown substance and/or behaving erratically.

Police believed medical assistance was needed and called for assistance from the Irondale Fire Department.

Officers rendered first aid on the scene until paramedics arrived. The man was then taken to St. Vincent’s East where he was pronounced dead at 6:34 a.m.

His cause of death is pending additional laboratory studies.

The Alabama Law Enforcement Agency is leading the investigation, which is standard policy for in-custody deaths.
