The OSBI is investigating an incident Saturday at McGee Creek State Park in Atoka County. Spokeswoman Jessica Brown tells KTOK News that campers complained to a park ranger about a man acting strange and causing a disturbance. The ranger confronted 30-year-old David Maher who would not cooperate. Brown says Maher ran to his vehicle and attempted to run over the park ranger. The ranger shot Maher at least one time. Maher was taken to a hospital where he died. Maher's last known address was in New York.
