A bus driver was acquitted Tuesday of homicide charges in the deaths of four passengers killed when his double-decker crashed into an overpass in upstate New York.

A judge announced the verdict after a non-jury trial for 60-year-old John Tomaszewski of Yardville, N.J. Tomaszewski would have faced up to four years in state prison on each of four counts of criminally negligent homicide. He sat with his head bowed and showed no reaction as Onondaga County Court Judge Anthony Aloi read the verdict.

"It was a tragic accident and four people lost their lives," Tomaszewski said as he left court. "It's something I'll have to deal with the rest of my life."

There were 29 passengers on the Megabus when the top of the bus hit the railroad bridge in Salina, just outside Syracuse, early on the morning of Sept. 11, 2010.

Tomaszewski was driving from Philadelphia to Toronto with a planned stop at the Regional Transportation Center in Syracuse when he missed an exit from Interstate 81 and ended up on the parkway instead.

Assistant District Attorney Chris Bednarksi said during the trial that Tomaszewski was using a personal GPS device as he tried to find his way to the bus station and passed 13 low-bridge warning signs, some with flashing yellow lights, before the wreck.

A federal judge blocked police in Arizona from enforcing a section of the state's 2010 immigration enforcement law that prohibited people from blocking traffic when they seek or offer day labor services on streets.

U.S. District Judge Susan Bolton ruled Wednesday that groups seeking to overturn the law will likely prevail in their claim that the day labor rules violate the First Amendment. She rejected arguments by the state that the rules were needed for traffic safety and pointed out that the law, also known as SB1070, says its purpose is to make attrition through enforcement the immigration policy of state and local government agencies.

"This purposes clause applies to all sections of SB1070, and nowhere does it state that a purpose of the statutes and statutory revisions is to enhance traffic safety," the judge wrote.

The ban was among a handful of provisions in the law that were allowed to take effect after a July 2010 decision by Bolton halted enforcement of other, more controversial elements of the law. The previously blocked portions include a requirement that police, while enforcing other laws, question people's immigration status if officers suspect they are in the country illegally.

The U.S. Supreme Court has agreed to hear Gov. Jan Brewer's appeal of Bolton's decision to put the most contentious elements of the law on hold. Another appeals court has already upheld Bolton's July 2010 ruling.
