At 112 mph, the speeding motorcycle rider blew by a CHP officer on the side of Highway 101 Sunday night, then continued her high speeds in an attempt to get away from the pursuing officer, said the CHP Monday.

The chase ended with the arrest of Santa Rosa woman, Whitney Beck, 25, who appeared to be drunk, reported CHP Officer Jon Sloat.

The officer saw the motorcycle at about 10:15 p.m. near central Windsor.

As the officer caught up to the rider, near Healdsburg, the rider took the Dry Creek Road exit but then ran a stop sign and got back onto the highway heading north, Sloat said.

She accelerated to about 100 mph until he gave up near Lytton Springs Road.

Beck was arrested on suspicion of drunken driving, reckless evasion and driving 30 mph over the posted speed while drunk, Sloat said.

Earlier Sunday a driver stopped for not wearing a seat belt turned out to be wanted on a drunken driving case, Sloat said.

Robert Pradd, 33, was stopped on Santa Rosa Avenue at about 5:10 p.m. for the violation.

Pradd is a former Santa Rosa resident who now lives in San Diego.

His license was suspended last year for a drunken driving conviction, Sloat said. Pradd also was wanted in Sonoma County for skipping out on court for the DUI case.

Pradd was taken to the Sonoma County Jail on the warrant and for driving with a suspended license.
