The recording was enhanced and evaluated by New Jersey-based audio experts Stuart Allen and Tom Owen at the request of The Plain Dealer newspaper. Both concluded that they hear someone shout, “Guard!” Seconds later, a voice yells, “All right, prepare to fire!”

“Get down!” someone shouts, presumably in the crowd. A voice then says, “Guard!…” followed two seconds later by a booming volley of gunshots.

Four Kent State students were killed and nine were wounded.

“I think this is a major development,” said Alan Canfora, who was shot and wounded in the right wrist during the protest on May 4, 1970. Canfora, who has long believed that the troops were ordered to fire, located a copy of the tape in a library archive in 2007 and has urged that it be professionally reviewed.

The original reel-to-reel audio recording was made by Terry Strubbe, a student who placed a microphone in a window sill of his dormitory that overlooked the anti-war rally.

Allen, president and chief engineer of the Legal Services Group in Plainfield, N.J., removed extraneous noises — wind blowing across the microphone, for example — that obscured voices on the recording.

Without a voice sample for comparison, the new analysis can’t determine who might have issued such a command or why.
