Fire Investigator McGroarty was in the attic of a residential structure that had experienced a fire five days prior. A private fire investigator and an electrical consultant were also in the attic with Investigator McGroarty. During the course of the investigation a chimney, which had been supported by the roof prior to the fire, collapsed onto Investigator McGroarty and inflicted severe injuries. The chimney was too heavy for the personnel on the scene to lift and it stayed in place until additional personnel arrived. Medical treatment was initiated immediately after Investigator McGroarty was freed and was continued at the hospital, to no avail. The cause of death on the autopsy was listed as multiple injuries due to falling debris from a recent fire. Additional information about this incident can be found in NIOSH Fire Fighter Fatality Investigation 99-F-06.
