“A Monster Of A Case” — Police Share Inside Information On Roxanne Sharp’s Murder

When the Roxanne Sharp murder case went cold, Louisiana State Police tried something unusual to help solve the 1982 killing: they partnered with a trusted local radio host in a small Louisiana town to launch a true crime podcast. In this episode of Criminally Obsessed, Anne Emerson speaks with Louisiana State Police PIO Marc Gremillion about how podcaster Charles Dowdy and the "Who Killed Roxanne?" podcast helped generate new leads in the decades-old cold case murder investigation. After Roxanne Sharp’s case was featured on the true crime podcast and shared across social media, tips started pouring in from Louisiana and across the country. Former Covington residents, people connected to the case, and even younger generations who had only heard rumors about the murder mystery began reaching out to investigators. Louisiana State Police say this was one of the first times the agency partnered so closely with a podcast during an active cold case investigation — and after seeing the response, they believe podcast collaborations could become an important tool in future murder investigations and unsolved cases. The Roxanne Sharp case is now one of the most compelling examples of how true crime podcasts and local journalism can help revive cold cases, reexamine crime scene evidence, and generate new leads. Do you think podcasts and true crime documentaries can help solve crimes? Could more police agencies begin partnering with local media and podcasters to reopen unsolved murder cases? Let us know in the comments.

Why It Took 44 Years (and a True Crime Podcast) to Bring Charges in Roxanne Sharp’s Killing

A murdered teenage girl. A cold case that went unsolved for more than four decades. After years without answers, Louisiana State Police tried something different: they helped launch a true crime podcast to generate new leads. Now, four men have been charged in connection with the 1982 killing of Roxanne Sharp. Roxanne was 16 when her body was found in a wooded area near the St. Tammany Parish Fairgrounds in Covington, Louisiana. According to Louisiana State Police, the initial investigation determined she had been raped and murdered, but due to limited physical evidence and a lack of public and witness cooperation, the case remained unsolved for more than four decades. That changed after Louisiana State Police took over the investigation and teamed with local radio host Charles Dowdy of the Lake 94.7 to produce the podcast "Who Killed Roxanne?" Authorities say the podcast generated new information, leads, and witness cooperation that had previously been unknown to investigators. In April 2026, arrest warrants were obtained for four men: Perry Wayne Taylor, Darrell Dean Spell, Carlos Cooper, and Billy Williams Jr., all of Covington, Louisiana. They were charged with aggravated rape and second-degree murder. In this episode of Criminally Obsessed, Anne Emerson speaks with the podcast's host, Dowdy, about the case, the podcast, and how storytelling helped move forward a murder investigation that haunted Louisiana for more than four decades.

Exclusive 'Secret' Interview: Alex Murdaugh's Alleged Co-Conspirator Still Awaiting Trial — Why?

WHO IS 'COUSIN' EDDIE? As Alex Murdaugh prepares for a murder retrial, why hasn't this alleged Murdaugh co-conspirator gone to trial in the first place?  Anne spoke with Curtis “Eddie” Smith, the man prosecutors say helped Alex stage a roadside shooting in Hampton County, South Carolina back in 2021. This is an exclusive interview Anne did in 'secret' that we unearthed from our archives that was conducted just weeks after the incident. Nearly five years later, the alleged co-conspirator in the failed $10 million life insurance plot remains on house arrest, with police claiming he was also pushing drugs, forging checks, and laundering money for Alex.  As the Murdaugh case heads back to court, this interview raises an even bigger question: why is one of the key figures in the saga still sitting in legal limbo? Murdaugh defense attorney Dick Harpootlian says a trial for Eddie is taking way too long. Subscribe to Criminally Obsessed so you never miss our continuing Murdaugh coverage.

Murdaugh Prosecutor's Strategy and Death Penalty for Alex?

ATTORNEY VS. ATTORNEY: It hasn't even been a week since the news came down that Alex Murdaugh is getting a murder retrial in South Carolina, and so much news around this case has already broke — from a six-figure lawsuit to, now, the fact that the death penalty is on the table for Alex in this trial sequel! A day after our sit-down interview with Murdaugh defense attorney Dick Harpootlian, we caught up with the other side of this case. Creighton Waters helped convict Alex Murdaugh in the murders of his wife, Maggie, and son, Paul in 2023. He’s now faced with trying the same case — but does the defense already know his playbook? Or are there new tricks up his sleeve? Waters reacts to the South Carolina Supreme Court ruling that former Clerk of Court Becky Hill improperly influenced jurors during the 2023 trial, and expresses frustration with how the actions of one court official destroyed the integrity of the verdict. If you know Criminally Obsessed, you know Anne has reported extensively on the Murdaugh saga - she reported from the courtroom on all six weeks of the original trial!
