OMAHA, Neb. (AP) — The Nebraska Supreme Court has vacated a felony manslaughter conviction for a dump truck driver who caused a fatal crash in 2012.

The high court said Friday that the trial judge was wrong to allow two traffic infractions — driving too fast for conditions and following too closely — to serve as the basis for Lyle Carman’s felony manslaughter conviction. The high court said those minor offenses would allow only for a misdemeanor motor vehicle homicide conviction.

Carman was convicted last December for the June 7, 2012, crash on Interstate 80 near Lincoln that killed 23-year-old Raven Addy-Cruz, of Kearney, and seriously injured her husband and year-old daughter. He was sentenced earlier this year to 3 years’ probation and 90 days in jail.
