GRAND RAPIDS, Mich. (WOOD) - Caffeine was the only substance found in the body of a helicopter pilot who died in a crash in a remote area of Oceana County in December, authorities confirmed to 24 Hour News 8.
Thomas Slocum was 49. His passenger, 28-year-old Matt Williams, was seriously injured but is recovering.
Lt. Craig Mast of the Oceana County Sheriff's Department confirmed the autopsy on Slocum showed he died from the injuries sustained in the crash on December 1, 2012.
The helicopter went down in a swamp in a remote area. Williams was able to get enough of a cell phone signal to call for help, and authorities used its GPS to pinpoint the crash.
It's still unclear exactly what caused the crash, though Williams told investigators he heard a loud noise right before the crash.
The helicopter was not able to be recovered until Jan. 6, 2013.
