CHEYENNE, Wyo. (AP) — A federal appeals court has upheld the convictions of a Utah man in connection with a naked rampage on Interstate 80 in south-central Wyoming.

A three-judge panel of the 10th U.S. Circuit Court of Appeals this week upheld the convictions of Armando Juan Cano of Moroni, Utah. He pleaded guilty last year to attempted carjacking and using a firearm during a violent crime.

Authorities say Cano rammed another vehicle, fired shots from a stolen handgun and ran naked in traffic. The nighttime rampage happened in June 2010.

The appeals court upheld Cano's 10-year sentence on the firearm count, but ruled that his 57-month sentence on the carjacking charge exceeded federal guidelines. The court ordered him resentenced under guidelines that set the maximum sentence for the firearm violation at 51 months.
