SHERMAN, Tex. -- Three accidents slowed down traffic on U.S. Highway 75 in Sherman on Thursday, with one traffic accident actually causing another.

Police say just before 2 p.m. a pickup truck may have run a red light at the intersection of U.S. Highway 75 and U.S. Highway 82, and somehow collided with another pickup. While officers were responding to that wreck, there was another crash involving four vehicles. One man was taken to Wilson N. Jones Hospital with minor injuries.

Another accident occurred Thursday at U.S. 75 near Taylor Street.

Police say two women were riding in a four-door Dodge when witnesses say a silver Honda swerved into another lane. The Dodge tried to swerve away, but instead went into a large ditch nearby.

The driver, 57-year-old Elda Spitznagel, of Bells, was flown to Parkland Hospital in Dallas.

The passenger, 40-year-old Kimberly Voyles, of Bells, was trapped, and firefighters used a rope as a life line to use with the steep embankment. Voyles was flown to Baylor Medical Center in Dallas.

Both women have serious but non life-threatening injuries.
