The Day the Radios Fell Silent: A Personal Account of May 26, 1978

It was a warm May morning in 1978. I was 15 years old, working the phones at my dad’s office at Camp Red Rock in western Oklahoma. For several days, law enforcement radio traffic had been intense—more active than usual, more urgent. Something serious was happening.

An All-Points Bulletin had been issued statewide: two inmates had escaped from the Oklahoma State Prison in McAlester. They were described as extremely dangerous men, capable of committing horrific crimes. The Oklahoma Highway Patrol (OHP) and local authorities launched a massive manhunt, focusing on the southeastern region of the state. While there were scattered reports from other areas, the belief was that the fugitives remained nearby and on foot.

Motor Vehicle Inspection (MVI) Division in Enid.

Still, troubling reports emerged—houses broken into, firearms stolen, and even a car gone missing. An army of troopers scoured the countryside. The fugitives had to move carefully, methodically, to avoid detection. The search had only been underway for days, but it felt like weeks.

May 26, 1978, arrived. It would become one of the darkest days in the history of the Oklahoma Highway Patrol.

Although I was hundreds of miles away from the action, the search was broadcast live to my ears. The ranger office where I worked was equipped with radios that picked up all law enforcement frequencies. I heard it all: the calls, the coordination, the chaos.

Trooper Billy G. Young, Woodward MVI detachment.

That morning, a somber message came over the radio from Highway Patrol District Headquarters:

“Attention all stations and units: All nets are 10-63 until further notice.”

In plain terms, this meant that the radio network was reserved exclusively for emergency traffic related to the escapees. No unnecessary chatter. But maintaining a “10-63 net” requires constant reinforcement. Officers rotate shifts. New dispatchers come on duty. Without reminders, the rule starts to fade, and soon enough, radio traffic returns to normal. That’s exactly what happened.

As the air unit tried to communicate with ground teams, their messages were drowned out by unrelated conversations. Then, something chilling unfolded.

Lieutenant Pat Grimes,
Internal Affairs.

I listened in real time. The air unit tried to warn a team of troopers. They had approached a area. The escapees were hiding—just beyond the trees, lying in wait. The troopers, thinking it was a routine check, got out of their car casually. Suddenly, gunfire erupted. It was an ambush.

One of the troopers managed to retreat to his vehicle and tried to call for backup. The air unit, having seen everything from above, struggled to get through. The radio frequencies were jammed with idle chatter. It was a communications nightmare that have cost lives.

I sat there, helpless, listening to the air unit reporting the tragedy to headquarters. The dispatcher pleaded for all units to clear the net so emergency aid is dispatched. I was stunned—devastated. This moment became a lasting lesson in why radio discipline can be a matter of life and death.

Later that day, I was shocked again—two more troopers had been shot in the same area. And then, I heard the message that signaled the manhunt was over:

“Be advised, the search for the escapees is over. All units and stations can return to regular assignments.”

That phrase said it all. The escapees were no longer a threat. They hadn’t been captured—they were dead. Had they been taken alive, the dispatch would have named the unit responsible for their arrest.

The Fallen

Three troopers lost their lives that day:

  • Trooper Houston F. “Pappy” Summers, 62, a 32-year veteran stationed with the Motor Vehicle Inspection (MVI) Division in Enid.
  • Trooper Billy G. Young, 50, with 25 years of service, attached to the Woodward MVI detachment.
  • Lieutenant Pat Grimes, 36, from Internal Affairs, nearing his 12th year with the Patrol.

Summers and Young died in a gunfight on a rural road near Kenefic. This occurred after the escapees stole a farmer’s truck and weapons. The troopers, unaware of what they were driving into, were ambushed.

Later that day, in the small town of Caddo, Lt. Grimes and his partner, Lt. Hoyt Hughes, were searching a residential area when they, too, came under fire. Grimes was fatally shot. Hughes was wounded but managed to exit the vehicle and return fire at close range, killing one of the fugitives.

Just moments later, Lt. Mike Williams of the Durant detachment arrived. He fatally shot the second escapee. This action brought an end to a 34-day reign of terror that had stretched across six states.

The two escapees caused the deaths of eight people. This number includes the three troopers. They also injured at least three others during their violent run from justice.


Final Thoughts

What I heard that day shaped me. During my time in the police academy, I learned something important. My account of the events closely aligned with what was eventually confirmed. The tragedy of May 26, 1978, became a case study. It highlighted the importance of radio discipline. The event also emphasized operational coordination and situational awareness.

But for me, it was more than that. It was personal. I was there—listening. And I will never forget the sound of silence that followed.
