The Michigan Court of Appeals has ruled in favor of the Oxford school district in a lawsuit that seeks to hold employees partly responsible for a shooting that killed four students and wounded others.

Colt Gray, who was taken to the Gainesville Regional Youth Detention Center, was charged as an adult with four counts of felony murder for the deaths of students Mason Schermerhorn and Christian Angulo, both 14, and teachers, Richard Aspinwall, 39, and Cristina Irimie, 53.
