COLLINSVILLE, Okla. – Federal investigators are on the scene of a deadly plane crash in northeastern Oklahoma trying to figure out what happened.

The crash killed two people Sunday evening just north of Tulsa.

Kansas State University officials have identified one of the victims as Chris Gruber, a KSU foundation member and director of development for the university’s veterinary school of medicine.

Dr. Ronald Marshall, a retired physician from Manhattan, Kansas, is believed to be the other victim.

The plane was registered in his name.

The single engine Mooney M-20 has just departed from Tulsa International Airport and was headed to Manhattan, Kansas, when it dropped off radar.

Witnesses said it was obvious the plane was in trouble ahead of the crash.
