New York Tour Bus Crash Kills 14 in New York

March 13, 2011— -- The fatal gambling casino bus crash that claimed 14 lives in New York this morning now looks more likely to have been caused by its driver falling asleep rather than, as he told police, a tractor trailer hitting the bus from behind and triggering the chain reaction that caused the bus to flip and have its roof sliced off by a heavy sign support, officials said.

According to officials, the driver of the tractor trailer says that the tour bus bus flew by him. It hit lane warning bumps and continued to swerve until it flipped, sources said.

There was no evidence, officials said, of the truck having hit the bus.

The accident happened at about 5:30 a.m. on the New England Thruway at the Hutchinson River Parkway in the Bronx.

The bus was heading southbound when it flipped on its side. It then skidded into the support post for a large highway sign. The post sliced through the length of the bus at the passenger seat level, officials said.

New York Police Commissioner Raymond Kelly said both the truck and the bus were moving at "a significant rate of speed," according to ABC station WABC-TV in New York.

Shamel Bookard and Ashanti Jackson, friends of Oferdel Williams, the driver of the bus, described him as the kind of person who is likely ovewhelmed with sadness at what happened.

"I'm sure he's greatly sorry for what did happen," Jackson told WABC-TV.

They said Williams is known for his courage.

"Years ago he ran into a burning building and saved a family, there was a girl, a grandmother in a wheelchair, he brought them out the fire," Bookard told WABC-TV.

"Our -- and the entire city's -- prayers, thoughts and sympathies are with the victims, and their families and loved ones," said New York City Mayor Michael Bloomberg in a statement.
