The Occupational Safety and Health Administration has opened an investigation into the death of a worker at a Rivian warehouse in Illinois this week, the federal agency told TechCrunch on Friday. The agency said the probe could take up to six months.

The man, identified by local authorities as 61-year-old Kevin Lancaster, reportedly died from “blunt traumatic compressional injuries” after getting pinned between a tractor trailer and a loading dock at the facility, which is located just a few miles from Rivian’s factory.
