Robert Bates, 73, faces a manslaughter charge in the shooting of Eric Harris during a physical struggle with other deputies April 2. In a videotape of the incident, the shot is heard before Bates says, “I shot him. I’m sorry.”

Bates said he meant to shoot Harris, 44, with his stun gun but drew and fired his handgun instead. It has been alleged in a report by the Tulsa World that Bates’ training records and firearms certifications were falsified, a charge Bates and his lawyer deny.

Bates, an insurance executive, has donated cars and other equipment to the sheriff’s office — and donated to the re-election campaign of Sheriff Stanley Glanz.
