Former Chattanooga Police Department Lt. Todd Royval died Monday, sources tell Channel 3.

During his 20-year tenure with the Chattanooga Police Department, Royval ran the anti-gang efforts that were part of the city's Violence Reduction Initiative.

Retired CPD Assistant Chief Tim Carroll served with Lt. Todd Royval for his entire police career. Royval was instrumental in starting the city's anti-gang unit.  “Sense of humor, good guy, always worked out, good shape. You would call and say ‘Hey I know this is last minute but can you do this?’ and he would get it done.”

Royval requested reassignment in late 2014, and ultimately retired from the force.

In 2007, Royval was instrumental in starting the department's Crime Suppression Unit — a unit responsible for tracking gang activity. He was also tasked with helping carry out an anti-crime initiative for the city's last administration before Chattanooga Mayor Andy Berke took office.

Chattanooga Police Chief, Fred Fletcher released this statement in regards to Lt. Royval's death: 

Last night the world lost a very special person, a brother and friend. Monday night retired Chattanooga Police Department Lieutenant Todd Royval passed away.  

Lt. Royval was loved by family and friends, respected by coworkers, and feared by bad guys.

Lt. Royval was a 20-year veteran of the Chattanooga Police Department, retiring in January of 2015. He was a man who absolutely loved being a cop, mentoring other officers and serving the community. In 2007, Lt. Royval was instrumental in starting CPD’s Crime Suppression Unit. He later played a key role in the Department’s initial implementation of Focused Deterrence principles through the Violence Reduction Initiative. His work throughout his tenure at CPD is greatly appreciated by me, my staff, Mayor Berke, and the community.  

CPD Chaplains stand ready to assist anyone who needs spiritual support in this difficult time. Our Victim Services Unit will be coordinating additional support for those of us who need it.   

This is going to be a very difficult time for both the Royval and Chattanooga Police families. Please keep the entire Royval family in your thoughts and prayers and respect their privacy as they continue to cope with the loss of their beloved husband, father, son, and brother.

He was a dedicated man -- survived by his wife, also a former police officer, and the couple's two sons. “Everybody is heartbroken; guys who worked around him and for him are devastated. He made a mark on this community," said Carroll. 
He was a man who left a lasting legacy to the people he served and the lives he touched. A shocking and heartbreaking loss to the Chattanooga community, “He is going to be missed. He left an impression on this Police Department, his family, the community. Everybody knows Todd. He was a gentleman, 100% a good man.”
