A Pennsylvania State Trooper has received one of the highest awards in law enforcement for the actions he took to stop a man who launched a deadly rampage last December, and ABC News has exclusively obtained the unedited footage from the dash-cam that was installed in the trooper's police cruiser.

It's a rare glimpse into the moments when police engage an active shooter, and put their own lives on the line to potentially save others.

On the morning of Dec. 21, 2012, an unemployed, former trucker allegedly walked into a church in Frankstown Township, Pa., and opened fire on a woman decorating the building's walls for a children's Christmas party. The man, Jeffrey Lee Michael, then allegedly killed two others away from the church.

As Trooper Timothy Strohmeyer and Trooper David Navaruk each sped to the scene, they passed Michael in his pick-up truck heading the opposite direction. He fired shots into both police cruisers, and broken glass flew into Navaruk's face, according to the Pennsylvania State Police.

Still, Strohmeyer and Navaruk turned their cruisers around and gave chase, hoping to catch up with the fleeing suspect.

Meanwhile, trooper Kevin Campbell was approaching Michael from the opposite direction. Upon seeing Campbell, Michael "accelerated his truck and intentionally rammed Corporal Campbell's patrol car head-on," trapping Campbell inside his own cruiser, according to the state police.

Campbell was a sitting duck, while Strohmeyer's cruiser can be seen on video approaching the collided cars. Hoping to divert attention away from his trapped colleague, Strohmeyer rammed his own cruiser into the back of Michael's truck, state police said.

Strohmeyer's plan worked. Michael can be seen on video charging Strohmeyer's cruiser with his gun drawn and firing. Eight bullets ripped through Strohmeyer's windshield, as shown in a photograph obtained by ABC News. Strohmeyer was hit several times in the chest and left wrist.

Strohmeyer was wearing a bulletproof vest and survived. Michael was killed by the troopers' returning gunfire.

Lucky pig, but glad he didn't die. There are some good men and women on the force. Pity there are also dickheads, but that's true of all walks of life.

that is one crazy fucker.

Jeffrey Lee Michael, a 44-year-old unemployed truck driver, lived on Juniata Valley Road in Geeseytown, a village 70 miles west of Harrisburg in south central Pennsylvania. Mr. Michael hadn't worked since being injured in a traffic accident in the spring of 2012. As Christmas approached, Michael had been behaving in a way that made his neighbors "uneasy." Health problems, a divorce, and child custody battles mixed with his apocalyptic beliefs based upon biblical prophecy and the ancient Mayan end-of-the-world calendar, had turned Mr. Michael into an unstable, unpredictable, walking time-bomb. Other than a few speeding tickets, Jeffrey Michael had not been in trouble with the law.

On Friday morning just before nine o'clock on December 21, 2012, Jeffrey Michael loaded several handguns into the cab of his pickup truck. Before driving off, he aimed one of the guns at the Juniata Valley Gospel Church across the road from his house, and fired a bullet through one of its windows. With a gun in hand, Michael walked across the street and entered the building where he encountered two women who had come to the church to decorate the interior for an upcoming children's Christmas party. Although he didn't know either of these church volunteers, Mr. Michael shot 58-year-old Kimberly Scott in the head, killing her on the spot. (The other woman either wasn't in the room at the time, or escaped being shot by fleeing the scene.) The dead woman's husband owned and operated the car dealership in nearby Duncanville.

Before climbing into his pickup, Michael approached Ken Lynn, a neighbor who was about to get into his car to go Christmas shopping with his wife. The 60-year-old neighbor, seeing Michael come toward him with a gun in his hand, tried to flee but was shot before he could get away. The calm, matter-of-fact gunman killed him with a single bullet to the head.

After randomly murdering Kimberly Scott and Ken Lynn, Jeffrey Michael got behind the wheel of his truck and drove north on Juniata Valley Road. Less than a mile from his house, after intentionally ramming into the rear of another pickup stopped at an intersection, Michael climbed out of his vehicle with a gun in his hand and approached the other driver, William Rhodes. Michael shot the 38-year-old construction worker in the head, killing him instantly.

Medical science and psychology really needs to get up to speed such that crazy fuckers like this can be pinpointed and apprehended before they kill innocent people.
