The family of a Kentucky EMT who was killed in an ambulance crash earlier this month has filed a lawsuit.

On April 1, a semi -- driven by Cory Dunn, 44, of Lexington -- made a left turn in front of a Somerset-Pulaski County ambulance that was headed north, according to Fox56. 

Driver/EMT Chastian Mcwhorter, 26, of Albany, and the patient,  Robert Caudill, 75, of Nancy, were prounounced dead at the scene. 

EMT Bailey Haynes, 23, and Dunn were transported with non-life-threatening injuries.

The suit alleges Dunn “failed to comply with regulations governing commercial vehicles including, but not limited to, regulations regarding driving commercial vehicles, general requirements, parts, and accessories for safe operation, commercial driver’s license standard, inspection, repair, and maintenance."
