A San Diego man was decapitated when he attempted to "plank" under a moving train two months ago, according to the coroner's report released Tuesday.
David Kenneth Mark Archuleta Jr., 41, was walking with friends when he crouched down next to the tracks.
Officials say Archuleta rocked back and forth and then tried to roll under the train. However, he failed to clear the box car and died instantly according to the report.
The San Diego County Medical Examiner said the victim and his friends had planned to film Archuleta "planking" under the moving train.
The San Diego County Sheriff’s Department investigated the incident that happened near Market Street and Harbor Drive on June 10 just before midnight.
A northbound Northern Santa Fe freight train was traveling northbound through downtown near the Embarcadero. The ME's report said the gate and lights used to warn pedestrians were operating normally at the time.
A toxicology report shows Archuleta had marijuana in his system at the time of his death.
An uncle told officials Archuleta lived a transient lifestyle who was known to live with his father from time to time.
