Two fourth grade teachers from Philadelphia Elementary School were injured Monday afternoon when their vehicle collided with a West Lauderdale School bus on Mississippi 19 south as they were returning home from a conference.

Philadelphia Superintendent of Education Terry Larabee said the two teachers, Wendy Smith and LeAnna Williams, had attended a conference at Mississippi State University-Meridian and were returning home when the accident occurred shortly before 4 p.m.

Smith was treated and released from Rush Hospital Monday night, Larabee said.

Williams remained in Anderson Hospital Tuesday.

Mississippi Highway Patrol spokesperson Andy West said the school bus was traveling eastbound on Rocky Ridge Road in Lauderdale County and was attempting to cross Highway 19 when the accident occurred.

"The bus had crossed the southbound lanes and was attempting to cross the northbound lanes when the other vehicle collided into the side of it and the bus overturned," West said.

"There were 11 students and the driver on the bus. Eight students and the two people in the car went to the hospital. No one sustained any life threatening injuries."

Williams and Smith had to be extricated from their vehicle by first response emergency personnel, Larabee said.

Students were evacuated through the alternate exits as the bus remained on its side.
