GULFPORT, Miss. (AP) -- D'Wayne Swear, a law enforcement officer in Louisiana and Mississippi whose career with the Naval Criminal Investigative Service led to a job as an adviser on the television series "NCIS: New Orleans," has died at age 60.

Bradford-O'Keefe Funeral Home said Swear died Tuesday at his home in Gulfport. His longtime friend Glenn Grannan of the Hancock County Sheriff's Office said Swear had recently been diagnosed with cancer.

"He never compromised his morals or his ethics," Grannan said Wednesday. "He only knew how to do things one way, and that was the right way."

Swear was a deputy with the Jefferson Parish Sheriff's Office in suburban New Orleans before working as an agent with the Naval Criminal Investigative Service. He retired from NCIS in 2010 and settled in Gulfport. He came out of retirement to work with the Hancock Sheriff's Office, said Grannan. In 2014, he became an on-set technical advisor for "NCIS: New Orleans."

"He's such a charming guy, so likeable," series star Scott Bakula said of Swear in a 2014 interview with NOLA.comThe Times-Picayune. "He's got great stories he loves to tell, and he loves this city."

Visitations and funeral Masses are set for Saturday in New Orleans and Monday in Gulfport.
