A man, whose mummified remains were found in a manhole last month, likely died of electrocution, an autopsy report states.

The body was “found with a pair of bolt cutters in his hands in an underground high voltage utility access with cut copper wires near the remains,” a report from the office of the Pima County Medical Examiner stated.

The man died between 12 and 24 months before his remains were found, said Dr. Gregory Hess, chief medical examiner.

Crews working near Tanque Verde Road and Tanque Verde Loop May 19 found the body when they opened the manhole, said a sheriff’s spokesman.

An identification card for a 51-year-old man was found with the remains, but the medical examiner’s offices is awaiting the results of a DNA test to verify the name of the deceased.
