A 53-year-od Amarillo man was killed in an accident at the city landfill yesterday.

Three trucks were unloading at the landfill when one of them became stuck.  Michael Shawn Lightfoot of Amarillo was outside of his truck helping to get the truck unstuck.  The truck was freed.  The driver of the freed truck then reversed and backed over Lightfoot and killed him instantly.

The driver of the truck had mistakenly presumed Lightfoot had already gotten back into his truck before he backed up.

An autopsy has been ordered and the incident is still under investigation.
