NAMPA -- A Weiser man pleaded guilty Thursday to misdemeanor vehicular manslaughter in connection to a violent wreck off a Nampa overpass that killed another driver last year.

Tyler Callahan, then 21, was headed west on I-84 March 29, 2016 when he lost control of his Chevy Impala, launching the car over the side of the overpass.

Callahan's car plummeted to the street below, landing on top of a pickup truck driving on Northside Boulevard.

The pickup's driver, 64-year-old John Pew of Nampa, was killed. Callahan and two young passengers in his car were hospitalized.

The misdemeanor charge was filed against Callahan in March, one year after the deadly wreck. According to the criminal complaint, read by a judge at Thursday's hearing, Callahan "commit[ed] the unlawful act of failure to maintain your lane and/or did drive down a median and/or was careless or inattentive in light of the circumstances in existence, without gross negligence."

The crime is punishable by up to a year in jail, a $2,000 fine, or both. In addition, Callahan's driver's license will be suspended for a length of time to be determined at sentencing.

The sentencing hearing is set for Tuesday afternoon.

Pew's family filed a tort claim against the Idaho Transportation Department after his death, arguing a concrete barrier in that area would have prevented the car from flying off the overpass.
