Holly Lynn Bobo (October 12, 1990 – April 13, 2011) was an American woman who disappeared on April 13, 2011, from her family home in Darden, Tennessee. She was last seen alive by her brother, Clint, shortly before 8 a.m., walking into the woods outside her home with a man wearing camouflage. In September 2014, Bobo's partial remains were found in northern Decatur County, and her death was ruled a homicide via a gunshot to the back of the head.

Six men have been arrested for varying degrees of involvement in the murder. However, only three of the six have been prosecuted. Most of the arrests were made on the basis of a confession by John Dylan Adams, a man with an intellectual disability. He told police he saw Bobo with his brother Zach and a friend, Jason Autry, at his brother's home after her kidnapping. It is unknown what led police to question Dylan about Bobo's disappearance. Dylan, Zach, and Autry were charged with especially aggravated kidnapping, first-degree murder, and rape. Of the other three men arrested, charges against two were dropped, and one committed suicide without any charges being filed against him.

The case has met with several setbacks, such as the death of a suspect, multiple changes to the prosecutorial team, and disputes with the Tennessee Bureau of Investigation (TBI). The prosecution has been heavily criticized for refusing to produce evidence against the defendants, missing multiple discovery deadlines, and making frequent changes to the charges against the defendants with little explanation. The TBI even briefly withdrew its services to the entire district after the prosecutor accused the agency of compromising the case by proceeding "so slowly that the culprits were always one step ahead and that TBI . . . was leaking information and possibly covering up evidence." Defense attorneys reported that they, over a year after the arrests were made, had still not received a bill of particulars detailing the case against their clients and the results of forensic testing done on evidence from the case. They hence filed motions to dismiss charges on the grounds of "silence or stonewalling". The arrests took place in early 2014, but it was not until July 2015 that it was announced that the defendants finally received access to all evidence against them.

On September 22, 2017, a jury found Zach guilty on all charges, including first-degree murder. He was sentenced to life imprisonment plus 50 years on September 23. He maintains his innocence. In January 2018, Zach's brother, Dylan, accepted an Alford plea and was sentenced to 35 years in prison. Autry chose to make a plea bargain with prosecutors, wherein he would testify against Zach in exchange for a significantly reduced sentence. On September 16, 2020, after accepting a deal that reduced his sentence to eight years of time served, Autry was released from Riverbend Maximum Security Institution in Nashville. Autry subsequently recanted his entire testimony against Zach and confirmed that he was then given access to the discovery material, allowing him to synchronize his testimony with the available evidence. In January 2024, Adams filed a petition that his conviction be overturned on the basis of this new evidence.

Background At the time of her disappearance, Holly Bobo was a 20-year-old nursing student at the University of Tennessee at Martin at The Parsons Center in Parsons. She lived with her parents and brother in Darden. Friends described her as shy and sweet. She was the cousin of country singer Whitney Duncan. In 2017, Duncan released a song called "Better Place" in memory of Bobo.

Disappearance On the morning of April 13, 2011, Bobo awoke at 4:30 a.m. to study for an exam. At 7:30 a.m., she answered a call from her boyfriend, Drew Scott, who was turkey hunting nearby on his grandmother's property. Bobo's parents had left for work by this point, and her brother, Clint, was still asleep. Twelve minutes later, Bobo made her last cell phone call. After this point, all phone calls and texts were incoming and unanswered.

Shortly after Bobo's final phone call ended, a neighbor heard a scream from the Bobo residence. The neighbor called his mother to tell her about what he heard, and the mother, in turn, called Bobo's mother, Karen, at work. Meanwhile, Clint was awakened by the family dogs barking and saw Holly outside with a man dressed in camouflage: "It appeared to be Holly kneeling down and Drew [Scott]. They looked like they were kneeled down, facing each other in the garage, and they were talking back and forth. Holly sounded very upset and heated. He was doing much of the talking, and she would answer back and things like that. I couldn't make out hardly any of the words. The only words I could make out from here were Holly saying, 'No, why? Clint said he believed that the couple were breaking up. At some point, Karen called home and spoke to Clint. She said, "Clint, that's not Drew. Get a gun and shoot him." Clint reportedly replied, "You want me to shoot Drew?", still believing that the man was Holly's boyfriend.

Karen called 9-1-1, but because she was calling from work, she reached a dispatcher for the wrong county. At home, Clint looked outside again and saw the man walking with Holly into nearby woods. At this point, he noted that the man was larger than Drew Scott. Clint tried to call his sister's cell phone as well as Scott's cell phone, but neither call was answered. When Karen called her house again, Clint told her what he witnessed and was instructed to call 9-1-1. Clint fetched a loaded pistol and went outside, where he found bloodstains belonging to Holly in the garage. He dialed 9-1-1. Police arrived at the Bobo residence ten minutes later.

Cell phone pings showed Holly's cell phone moving away from her home tower, heading north. Her cell phone continued north to a wooded area near Interstate 40, where her remains were eventually found. After her cell phone stopped moving for 20-30 minutes, it began traveling south again using a different route. The last cell phone ping came from Holly's phone in the area where both the phone and its SIM card were later found.

Investigation Clint described the man as being between and tall, weighing , and having dark hair sticking out from under his cap that was long enough to cover his neck and touch his collar. Clint said that the man was wearing a hat and camouflage clothing from head to toe and identified the pattern as either Mossy Oak break up or leafy wear. He described the male voice he heard as very deep and low.

Extensive searches of the area were conducted after Bobo's disappearance. Several items belonging to Bobo were found scattered throughout the town, including her lunchbox, a receipt with her name on it, a card from school, her cell phone, and a SIM card, which had been removed from the phone.

Early in the investigation, the Tennessee Bureau of Investigation (TBI) focused heavily on a registered sex offender named Terry Britt, who matched the witness description. His home was wiretapped and searched during the course of the investigation, but he was never charged.

In September 2014, Bobo's partial remains were found by ginseng hunters in a wooded area of northern Decatur County, Tennessee, just off I-40, nearly 20 miles (32 km) from Darden. The owner of the property, Gary Tubbs, said it was not uncommon for people to hunt there without permission. Larry Stone, one of the men who found the remains, said he saw a large bucket in the woods, which he upturned. Beneath the bucket, he found a human skull. He then spotted Bobo's remains spread on the ground behind him. Investigators recovered Bobo's skull and teeth, several ribs, and one shoulder blade. Her skull had a bullet hole in the back of it; the bullet entered the back-right side of her head and traveled to the front-left side, fracturing her left cheekbone when it exited.

Arrests Six men have been implicated in connection with Bobo's disappearance. The first arrest occurred in March 2014 before the discovery of Bobo's remains. Zach Adams, his brother Dylan Adams, and friend Jason Autry were ultimately charged with especially aggravated kidnapping, first-degree murder, and rape. Another two men, Jeffrey and Mark Pearcy, were arrested on charges of accessory after the fact and tampering with evidence; however, charges against the Pearcy brothers were dropped. Another man, Shayne Austin, committed suicide.

It is unclear what initially led law enforcement to suspect these men, but the investigation began with the arrest of Dylan Adams on unrelated weapons charges. After this arrest, he told police that he witnessed Bobo alive with his brother at Zach's home after her abduction. An affidavit for a search warrant states that Dylan told authorities that on April 13, 2011, he went to Zach's residence to get his truck. Dylan reportedly "observed Holly Lynn Bobo sitting in a green chair in the living room wearing a pink t-shirt, with Jason Wayne Autry standing just a few feet away." He also told police Zach was "wearing camouflage shorts, black cut-off-sleeve t-shirt and a pair of green Crocs". Dylan also said that Zach told him "he had raped Bobo and videotaped it." The alleged videotape has not been found. Dylan later recanted the confession and alleged that he was coerced, but his confession led to the arrests of Zach Adams, Jason Autry, and Shayne Austin. Many details contained in the confession were eventually found to be inconsistent with the known evidence, and the narrative presented later in court was vastly different. In early 2017, it was announced that Jason Autry had agreed to testify against Zach in exchange for leniency.

In 2014, District Attorney Matt Stowe said he and the TBI were still "actively looking" to bring criminal charges against additional people, although he declined to name the parties or the charges.

Shayne Austin Shayne Kyle Austin was initially offered immunity in exchange for information regarding the location of Bobo's body. Phone records indicate that Austin was in contact with Adams several times on the day of Bobo's abduction, and police believed that Austin helped dispose of the body. The agreement was withdrawn after Austin was unable or unwilling to lead them to the body. The district attorney released a statement saying that Austin had "not been completely truthful, candid, forthcoming or cooperative as to any and all aspects of [the] investigation". In April 2014, Austin's attorney filed a complaint against the state, asking for an immediate and permanent injunction preventing the state from charging Austin. In February 2015, Austin was found dead from suicide in a hotel room in Bartow, Florida. Austin's attorney blamed the suicide on continual threats of prosecution as well as investigators' "witch hunt" style, saying they relied on rumors instead of evidence. The attorney insisted that Austin had nothing to do with the murder and cooperated fully with police.

Jeffrey and Mark Pearcy In July 2014, Jeffrey Pearcy and his brother Mark Pearcy were arrested and charged with accessory after the fact and tampering with evidence. They were arrested on the basis of allegations made by Jeffrey's former roommate, Sandra King. She claimed that in May 2014, Jeffrey showed her part of a video in which Adams assaulted Bobo, who was tied up and crying. King told police that she watched only a small clip and did not see the sexual assault. Police arranged for her to make a recorded call to Jeffrey, in which she told him, "That video of Holly, if it had been you, I would have watched it." She said that he replied, "I know." King alleges that Pearcy's brother Mark shot the video.
