Sgt. John Mattingly is a retired 21-year veteran with the Louisville Metro Police Department in Kentucky. Sgt. Mattingly spent most of his career in narcotics and violent crime units trying to improve the quality of life for the citizens of the city he grew up in and loved. On March 13, 2021, Sgt. Mattingly was thrown into the national spotlight when he was shot while executing a search warrant at the residence of Breonna Taylor. The national and worldwide exposure and protests that stemmed from that tragic evening were amplified by the death of George Floyd. The lack of transparency by the police department and city, allowed speculation and outright lies to be compounded by the media, social media, celebrities, and athletes.

In an attempt to correct the record, he wrote a book, 12 Seconds in the Dark, that will be released March 15, 2022, and is currently available for pre-order on Amazon.

John has been married to his wife Nicki for 15 years, has 4 children, and has 2 grandchildren.
