Matt Nemeth / 90.5 WESA

A man smoking a cigar laced with synthetic marijuana when he caused a chain-reaction crash that killed a University of Pittsburgh professor must spend five to 10 years in prison.

Fifty-year-old David Witherspoon was sentenced by an Allegheny County judge on Thursday after pleading guilty in February to involuntary manslaughter and other crimes in the October 2015 crash that killed 34-year-old Susan Hicks.

Witherspoon and his attorney say he is remorseful and has suffered from mental health issues.
