BOSTON -- A Metrowest man charged with his fifth drunken driving offense was cleared of all charges on Monday, in large part because witnesses in the case were summoned on the wrong date, according to a local paper.

Bryce R. Williams II, 45, of Westborough, was found not guilty Monday of drunken driving, leaving the scene of a property damage accident and driving with a suspended license.

Timothy Connolly, spokesman for Worcester District Attorney Joseph D. Early Jr., told the Telegram and Gazette that "there were some problems" regarding the prosecution's handling of the case.

"First and foremost, there was an error in summoning the witnesses for April 29, rather than April 14," he said.

Without any witnesses, the case was decided by the judge solely on the police reports, Connolly said.

Prosecutors said that Williams drove his green Toyota Tacoma pickup truck through a stop sign and hit another car in April 2007. Police later found the smashed pickup in a movie theater parking lot, with the keys in the ignition, the doors unlocked with an open can of beer, the paper reported.

When police questioned Williams at his home a short time later, they said he admitted driving the truck and that he had "too much to drink," the paper said. Police said Williams failed several field sobriety tests and refused to take a breath test.

But since police did not see Williams driving the truck and the witnesses were not in court, the judge ruled in his favor.
