Whitehorn was born in St. Louis, but moved to Shreveport in 1979. He served in the U.S. Air Force for four years, and then joined the Louisiana State Police. After serving in several different capacities, he became the Commander of Louisiana State Police in 2000. Mayor Cedric Glover chose Whitehorn to lead Shreveport Police over 18 other candidates in May.
As Chief, Whitehorn will oversee a department of more than 800 personnel and a budget of more than 46 million dollars.
Interim Chief Mike Van Sant will return to his duties of Assistant Chief. He has been serving as Interim Chief since Chief Mike Campbell resigned in November.
On Wednesday afternoon, Whitehorn will meet with police officers and clergy.
