Wiley graduated from Oak Grove High School and moved to Virginia with her first husband, working alongside him as a clerk for the Federal Bureau of Investigation. After moving back to Alabama and divorcing, Wiley continued to work as a secretary before applying to the police academy in August 1991. She was assigned to the West Precinct upon graduation in February 1992, but was quickly selected for undercover work with the department's Vice and Narcotics Unit. While working in that unit, she met her second husband, Jerry Wiley. They married in 1995 and she was transferred to the drug interdiction program at the Birmingham International Airport. She was honored as the department's "Detective of the Year" in 2004 and given the BPD Police Star Medal by Chief A. C. Roper in 2009.
Wiley retired in 2017. Over the course of her 24-year career as a vice detective, she was credited with the seizure of more than $36 million of illegal drugs, including 4,730 of marijuana, 27.5 kg of cocaine, 4.5 kg of methamphetamine, 2.4 kg of heroin, more than 80,000 tablets, and more than $300,000 in cash from illegal drug sales operations. She was also remembered for her compassion for people she interacted with as a detective and her generosity in supporting programs to provide clothing and blankets to the needy.
