A Louisiana State Police lieutenant was injured while getting out of his marked SUV on Interstate 10.
Trooper Melissa Matey says Lt. Robert Hodges was struck Saturday when a driver swerved onto the right shoulder in an apparent effort to avoid upcoming slowed traffic.
Hodges is being treated at East Jefferson General Hospital.
Matey says 20-year-old McCaskill, of Donaldsonville, was driving a car in the left lane of the highway. Troopers say traffic in front of McCaskill began to slow down, and he swerved into the right lane and right shoulder.
