A Tecumseh, Oklahoma police officer died on Monday after he was wounded in a shootout overnight, police said.
He has been identified as Officer Justin Terney, 22.
The officer made a traffic stop late Sunday when a man ran from the officer, Tecumseh Assistant Police Chief J.R. Kidney told CNN.
The officer used a Taser on the suspect but he was able to scramble into a wooded area. The officer and the suspect later traded fire, Kidney said.
The officer and suspect were transported to Oklahoma University Trauma Center in Oklahoma City.
