Former Pittsburgh news anchor Don Cannon, already facing sentencing for two drunken driving convictions in Allegheny County, pleaded guilty yesterday in California to his fourth DUI and is likely headed to jail under California law.

Prosecutors said Mr. Cannon, whose real name is Donald Clark, entered the plea in San Diego to a DUI charge from a May 16 arrest near his home in Carlsbad, where police said his blood-alcohol level was 0.31.

On Nov. 17, Mr. Cannon had pleaded guilty to another DUI near his home on March 29, when police said his level was 0.32.

California's legal limit is 0.08.

Under the California penal code, a fourth DUI arrest in 10 years is a felony carrying a penalty of up to three years in prison.

On the same day that he pleaded guilty in the March 29 case, police arrested Mr. Cannon, formerly of Upper St. Clair, on two outstanding bench warrants from Allegheny County related to two DUI convictions here.

The warrants said he had failed to report for 93 days of house arrest that he had to serve for DUI convictions in 2007.

Mr. Cannon pleaded guilty to both cases before moving to California but failed to complete his sentence.

He is scheduled to appear in court here on Dec. 18 and will be sentenced in San Diego on Jan. 15. His lawyer in California did not return a call yesterday.
