Crook is a Sharp County native and a graduate of Highland High School. After serving in the United States Air Force, Crook began his law enforcement career in 1988 as a jailer and dispatcher for the Sharp County Sheriff's Department.
In 1991, Crook became the Ash Flat Chief of Police and served in that capacity for 12 years. Crook helped expand the then one-man department into a three officer full-time law enforcement agency.
Crook also worked as a chief deputy from July 2005 to May 2006 under Sharp County Sheriff Dale Weaver.
In 2006, Sgt. Crook went to work for the Civilian Police International and traveled to Serbia where he worked under the direction of the United Nations Interim Administration in Kosovo. While in Kosovo Crook supervised a 9-1-1 type command center, managed schedules, wrote evocations and mentored international police officers from UN countries, 25 Kosovo officers and 19 language assistants. "This was, by far, the most challenging and rewarding part of my law enforcement career," Crook said.
Crook returned to the United States in 2007 and became the director of the re-established Third Judicial Drug Task Force. He worked with the DTF until his second trip to Kosovo in July 2008, where he worked as an investigator with the Organized Crime Unit until the UN control of the Kosovo administration was put in control of the European Union.
Crook came back to the United States and became a patrol sergeant with the Cherokee Village Police Department, where he remained until his promotion to Cherokee Village Police Chief last week.
Crook said that although he has enjoyed working with police officers in other countries and his experiences there, he is ready to stay in the United States and serve the citizens of Cherokee Village.
He said he hopes his experience will be an asset to the people of the city of Cherokee Village.
