A mother was charged with child neglect after her unsupervised 6-year-old son was throwing rocks at cars and darting in front of traffic before he was struck by a school bus Monday.

Russi allowed the boy and his 7-year-old brother to walk alone to the bus stop at Las Vegas Boulevard near Cheyenne Avenue.

Sandoval bucks GOP

Breaking ranks with his fellow Republican governors, Brian Sandoval said he will support expanding Medicaid eligibility in Nevada as called for under the federal health care law to provide coverage for the state's neediest residents.

Sandoval told the Associated Press that while he opposed the health care law, his decision will help tens of thousands of Nevadans.

The first-term governor said expanding coverage will add 78,000 residents to the state's Medicaid rolls but will save the state $16 million in mental health programs that otherwise would be paid for out of the state general fund.

Thousands of people got married or otherwise tested their luck in Las Vegas to mark 12/12/12, the last time in this century that numbers on the calendar will line up like that.

Nearby at University Medical Center, Briana Suarez was born by cesarean section at 12:12 p.m. on 12/12/12. She declined comment.

FBI raids limo company

The owner of a limousine service and two of his top aides were among those arrested by FBI agents in a multimillion-dollar racketeering conspiracy involving allegations of prostitution, drug trafficking and fraud.

Charlie Horky, 52, the CEO of CLS Las Vegas, a limousine service operating here since 1994, was released on his own recognizance after pleading not guilty in court to conspiracy and fraud charges.

The company calls itself a 24-hour chauffeur service that has contracts with a dozen Strip resorts.

Police visit schools

Las Vegas police sent officers to all 300 public and private schools in the city to ease fears after a gunman walked into an elementary school 2,500 miles away in Newtown, Conn., and killed 20 children and six adults . He had killed his mother earlier.

Police had no word of a copycat but mobilized to "lower the fear," said Deputy Chief Kevin McMahill, noting that parents and those at schools were noticeably on edge.

The Clark County School District has its own independent police force of about 140 officers, but district police often partner with city police and allow access to campuses, as it did Friday, school police spokesman Lt. Ken Young said.
