TUCSON, Ariz. - City prosecutors say all charges have been dropped against Arizona's All-America running back Ka'Deem Carey in a domestic violence case.
Carey was facing misdemeanor assault and disorderly conduct charges stemming from an alleged domestic violence incident in December involving his ex-girlfriend.
The Tucson City Prosecutor's Office issued a statement Friday saying it was dismissing all charges against Carey.
The statement said that ``a key witness for the prosecution is unavailable and even if the witness were available, there is no substantial likelihood that a judge would convict Mr. Carey.''
As a sophomore for the Wildcats last season, Carey led the nation in yards rushing with 1,929 and set a school record with 23 touchdowns.
He nearly became the 16th running back in NCAA history to reach 2,000 yards in a season.
