After 30 years, investigators are still searching for the killer of Melissa Witt in Arkansas.

Despite nearly 30 years passing, Melissa Witt's killer remains at large. In December 1994, the 19-year-old was abducted and murdered on her way to an Arkansas bowling alley to surprise her mother.

In the Fort Smith Bowling World parking lot and in Witt's abandoned car, investigators discovered blood and indications of a struggle. A set of keys belonging to the teen were left behind.

In 2021, JC Rider, a retired Fort Smith Police Department detective who was the lead investigator in the case, revealed to THV11 that the suspect was running low on money and planned to have her mother buy her a hamburger.

Rider stated that the trail led from the rear of her car to the location where the villain's car was parked.

Six weeks after her disappearance, her body was found by trappers, 50 miles away on a logging trail in the Ozark National Forest. She had been strangled, robbed of her shoes, clothing, jewelry, and even her Mickey Mouse watch.

The new Hulu docuseries "At Witt's End – The Hunt for a Killer," which premiered on Tuesday, focuses on the investigation into the murder of Witt and the subsequent search for her killer, featuring exclusive interviews and never-before-seen footage.

Charlene Shirk, a former reporter at KFSM-CBS, stated in the documentary that she was an ambassador to her college, meaning the college sent her to recruit students like her. She worked after school and was already a hard worker. She had big dreams for her life.

"She met her mom at a bowling church league, which is what we're taught to do as young people: get a good education, work hard, have a close relationship with our parents, and be a good kid."

After three decades, the Fort Smith, Crawford County, Sebastian County, and Van Buren police departments continue to collaborate with the FBI in the search for Witt's murderer.

The series portrays detectives investigating a local serial killer's reign of terror in a small-town Arkansas community before and after Melissa went missing, as stated in a Hulu press release.

In the 1990s, Charles Ray Vines, also known as the River Valley Killer, brutally murdered two elderly women in Arkansas counties. He was eventually caught in 2000 after attacking a 16-year-old girl. During the attack, the girl's stepfather tried to kill him, but was stopped by sheriff's deputies, according to KNWA.

In 2019, FBI agents focused their investigation on Vines while attempting to solve Witt's case.

"FBI agent Rob Allen stated in the documentary that a lady who worked with Charlie Vines' mother had emailed a detective. She reported seeing Charlie Vines wearing a bowling league shirt at his mother's work."

The police informed the filmmakers that vines had created maps of the Ozark Mountain region and had finished a work order close to where Witt's body was found, just an 8-minute drive away.

Police discovered a mattress cover and a Cambridge-brand cigarette filter with Vines' DNA at a nearby location during their investigation of the site where Witt was found.

According to the documentary, Vines, who passed away in September 2019, was unable to speak to detectives from various departments due to being ill and unconscious when the leads were discovered.

The teen's mysterious killing was not only led by vines, but also by other factors. Author LaDonna Humphrey, who has written three books on the case and produced her own documentary, "Uneven Ground: The Melissa Witt Story," has her own theory.

Witt's romantic partner, who is unnamed by authorities, is believed by Humphrey to have been the one who killed her.

Humphrey informed Newsweek that the unidentified man was not 10 years older than her, and he speculated that the man had a criminal past but was not currently incarcerated.

Despite the documentary's "different direction," the author stated that she is "really excited and hopeful" that the new release will "bring more eyes and more awareness to Melissa's case."
