Police say DNA work and a true-crime series helped lead to four arrests tied to the 1982 rape and murder of Roxanne Sharp in Louisiana.
Cold cases can feel like history once the facts go quiet—until a new method or new conversation pulls them back into focus.
Investigators say four men have been arrested and charged in the 1982 rape and murder of 16-year-old Roxanne Sharp, a case that went dormant for more than four decades before DNA testing and a true-crime podcast helped generate fresh leads.
Sharp’s body was found on Feb. 12, 1982, near the St. Tammany Parish Fairgrounds in Covington, Louisiana. Police allege she was raped and strangled. When the killing was investigated at the time, investigators had little physical evidence to work with, and no one was held accountable for the crime.
The case resurfaced decades later through a combination of old-fashioned detective work and modern forensics.. In 2023. detectives with the Louisiana State Police’s Covington field office reinterviewed witnesses and potential suspects. reviewed the case file in depth. collected additional evidence. and resubmitted original materials for DNA analysis.. The goal. investigators said. was straightforward but demanding: to see whether biological evidence that was previously unusable could yield answers under newer testing capabilities.
Misryoum understands that the breakthrough phase also required a public-facing push.. Two years after that renewed review began. detectives with the LSP public affairs and cold case unit partnered with local radio host Charles Dowdy of the Northshore Media Group to produce the podcast “Who Killed Roxanne?” Police say the series generated new information. led to additional witness cooperation. and surfaced details that investigators had not previously been aware of.
Arrests followed this month.. On April 21, Billy Williams Jr., 62, was taken into custody in Covington.. Darrell Dean Spell, 64, was arrested at his home in Dayton, Ohio, and is awaiting extradition to Louisiana.. Perry Wayne Taylor. 64. and Carlos Cooper. 64—both of Covington—were already incarcerated through the Louisiana Department of Corrections on unrelated charges. and police said they made contact with detectives on April 22.. All four men were charged with aggravated rape and second-degree murder.
For Roxanne’s family, the pace is likely hard to measure in years because of how long the uncertainty lasted.. But for law enforcement. a timeline of 40-plus years can still be expressed in practical steps: preserve evidence. revisit testimony. retest when technology improves. and keep the human network around the case from turning into a dead end.
Covington Police Chief Michael Ferrell credited that persistence.. He described the case as a demonstration of what happens when agencies refuse to let a victim be forgotten. saying cold cases don’t close themselves and instead close when people continue working year after year.. Misryoum notes that the chief’s framing matters because it shifts the conversation away from “one big break” and toward a system that can keep pressure on even when outcomes seem unreachable.
District Attorney Collin Sims echoed that theme, pointing to persistence, collaboration, and investigative technology.. He said Roxanne and her family waited for answers for more than four decades and that the arrests reflect an ongoing commitment to pursue justice regardless of how long it takes.. From an editorial perspective. that message also signals how prosecutors and investigators may think about future cold-case work: when evidence is scarce at first. the strategy becomes patience plus reinvestigation. not just a single attempt to solve the case.
The case has also prompted renewed attention on a modern pipeline for tips—podcasts and audio storytelling that can reach audiences far beyond traditional tip lines.. Unlike a standard press conference. a narrative series can keep a case in circulation. encouraging people who might not volunteer information to revisit what they remember.. Misryoum sees this as part of a broader national trend in which true-crime media. when paired with law enforcement engagement. can function as a conduit for witness recollection and new lead generation.
Still, the legal process remains the next crucial step.. Charged suspects are not convicted. and the outcome will depend on how the case is proven in court. including how prosecutors rely on DNA results. witness testimony. and any other evidence gathered during the renewed investigation.. Even so. for Roxanne Sharp’s family and community. the arrests mark a rare and powerful shift—from waiting to action.
DNA testing and reinvestigation restart the clock
Police say investigators returned to the Sharp case after a long gap by reexamining witness accounts, reviewing the full file, gathering additional evidence, and re-submitting materials for DNA testing in 2023.
A podcast becomes a new bridge to information
Misryoum reports that police partnered with radio host Charles Dowdy to produce “Who Killed Roxanne?” and credited the podcast with generating tips and witness cooperation.
The arrests end decades of uncertainty—now comes court
With four men charged in connection to the 1982 killing, the focus shifts to prosecution and evidence in court, even as the case underscores how technology and persistence can reshape old investigations.
