Authorities say a former police investigator whose work helped exonerate six people wrongly convicted of the 1985 rape and murder of a Beatrice woman has died following the crash of his pickup truck.
Fifty-four year-old Mike Oliver died after being found unresponsive Friday afternoon in his truck after it had crossed the U.S. Highway 77 median and rolled into a field.
Authorities say an autopsy Saturday showed Oliver had died of a medical episode, not from injuries in the crash.
The longtime Beatrice Police Department veteran had headed the task force that re-examined the investigation regarding the so-called Beatrice Six case.
