A father's attempt to teach his son a lesson for taking his truck without permission ended in tragedy Monday after a local police officer shot the teenager dead.

James Comstock of Iowa says he called the police on his son Tyler after he drove off with his  work truck in retaliation for refusing to buy him cigarettes.

Ames Police Officer Adam McPherson reportedly spotted the lawn care company vehicle and pursued it onto the Iowa State University campus, where a brief standoff ensued after Tyler allegedly refused orders to turn off the engine.

McPherson eventually fired six shots into the truck, two of which struck Tyler who was later pronounced dead.

"He took off with my truck. I call the police, and they kill him," James said. "It was over a damn pack of cigarettes."

McPherson is currently on paid leave pending the results of his department's investigation.
