Swear was a law enforcement officer and an agent with the Naval Criminal Investigative Service in addition to an adviser on 'NCIS: New Orleans.'

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 CBS television series NCIS: New Orleans, has died. He was 60.

Bradford-O'Keefe Funeral Home in Biloxi, Mississippi, 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 the NCIS in 2010 and settled in Gulfport. He came out of retirement to work with the Hancock County Sheriff's Office, according to 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.com/The 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.
