He went on to work in the department's Street Crimes Division, now the Special Enforcement Unit, where his primary tasks were investigating and arresting street-level drug dealers. Later, he was assigned as a task force officer with the Drug Enforcement Administration.
He has also served as a patrol shift commander and commander of the department's Housing Division. Napier is a 2007 graduate of the FBI National Academy.
He has served three stints with the Metro Drug Unit. In 2000 he served as an investigator; in 2005 he served as a supervisor; and in 2009 he served as commander.
He has worked on hundreds of drug-related arrests and said he enjoys his work.
"On Sunday I'm looking forward to going into work on Monday," he said. "I enjoy drug work, I really do."
While in Washington, he called back several times to check in with officers to hear how cases were progressing.
The unit has seized about 400 pounds of pot so far in 2012, but Napier said seizures are skyrocketing in heroin, prescription pills and meth.
Napier said about 500 grams of heroin were seized this year. In 2008, less than 50 grams was seized. The unit also took in more than 20,000 pills this year, as opposed to the 12,000 seized in 2011.
So far this year, officers have reaped 1,400 grams of meth. It used to be more like 100 grams per year.
The full-time drug interdiction team he created seized more than $400,000 in cash and $500,000 in drugs last year.
Napier also trains officers around the state in the methods and tactics used by the Metro Drug Unit. When he's not doing that, he goes to schools to speak to students about illegal drug use. He said some weeks he'll have three or four engagements.
"There's not a school I won't talk to, but I like to put an emphasis on middle schools," Napier said. "I won't turn down high schools, but I really try to seek out middle schools. That's the age where this stuff will be introduced.
"That combined with peer pressure, makes it extremely important to talk with them."
He also doesn't turn down opportunities to speak with professionals, especially those in the health care field.
"I just enjoy trying to make a difference," Napier said.
