8 killed when bus carrying 53 farmworkers crashes, 'high probability' for more deaths

Eight people were killed when a bus carrying about 53 farmworkers was hit by a truck and overturned on West Highway 40 in central Florida, according to state officials.

The truck driver, Bryan Maclean Howard, was arrested on eight counts of driving under the influence-manslaughter, the Florida Highway Patrol said.

Thirty-eight people were hurt, eight of whom are in critical condition and 30 who have non-life-threatening injuries, according to Marion County Fire Rescue.

There's a "high probability this may be beyond eight fatalities," Florida Highway Patrol Lt. Patrick Riordan, told reporters.

Howard was among those hospitalized, officials said.

Around 6:35 a.m., the 2010 International Bus and Howard's 2001 Ford Ranger truck were heading opposite directions when the truck veered toward the center line and the vehicles collided "in a sideswiped manner," officials said.

The bus veered off West Highway 40, went through a fence and then overturned, officials said.

The bus was en route to a farm in the area at the time of the crash, Riordan said.

Some of the farm workers involved in the crash were Mexican, according to Mexican Foreign Affairs Secretary Alicia Bárcena. The Mexican consulate in Orlando said it is helping support those affected.
