A young woman is missing in Myrtle Beach, South Carolina, and the case has taken a series of 𝓈𝒽𝓸𝒸𝓀𝒾𝓃𝑔 turns that have left investigators, family, and the community reeling. Twenty-year-old Heather Elvis vanished in the early hours of December 18, 2013, after what appeared to be a routine date, but the dark undercurrent of a twisted love triangle involving a married man and his jealous wife has turned this disappearance into a national headline.
Heather Elvis was a vibrant 20-year-old hostess at a popular Myrtle Beach restaurant, known for her passion for makeup and her love of work. Her parents, Terry and Debbi Elvis, described her as a proud young woman ready to take on the world. But beneath her bright future lurked a secret she tried to hide from those closest to her.
She had fallen into a tumultuous 𝒶𝒻𝒻𝒶𝒾𝓇 with Sydney Moore, a 38-year-old maintenance worker at her restaurant who was nearly twice her age.
Briana Witherspoon, Heather’s roommate and best friend, broke her silence exclusively about the case, describing how Heather’s romance with Sydney began. It was love at first sight for Heather, Briana recalled. From the moment they met when Sydney was hired for maintenance work, Heather was smitten.
Every time he came in, she would light up, running to Briana with excitement over every small interaction. Sydney made Heather feel like she was his one and only, but there was one huge problem: Sydney was already married.
The 𝒶𝒻𝒻𝒶𝒾𝓇 did not stay hidden for long. According to Briana, Sydney’s wife, Tammy, quickly discovered the relationship and unleashed a torrent of threats against Heather. Tammy texted and called repeatedly, warning Heather to stay away from her husband.
One text read in part, “Someone’s about to get their beat down. Your is about to take his last breath.” Tammy escalated the harassment by sending explicit photos of her and Sydney together, and she forced Heather to end the 𝒶𝒻𝒻𝒶𝒾𝓇 in a humiliating phone call where Sydney himself told Heather she meant nothing.
Heather was devastated. Briana recalled two months of non-stop tears as Heather tried to move on. Then, on the night of December 17, 2013, Heather seemed to be turning a corner.
She called Briana excited about a date she had planned. Briana asked what they were going to do, and Heather replied, “I’m not sure, but I’m just excited.” During the date, Heather texted Briana a picture of herself driving a manual truck with the caption, “Look at me, I’m a pro.”
It would be the last image anyone ever saw of her alive.
Heather’s date dropped her off at her apartment around 1 a. m. on December 18.
At 1:44 a. m. , Briana received a tearful phone call from Heather.
Heather told her that Sydney had called, saying he left his wife and wanted to see her. Heather was confused and upset, unsure what to do. Briana advised her to sleep on it, and they ended the call with their usual “love you.”
That was the final time Briana ever spoke to her best friend.
Phone records later revealed a chilling timeline. At 1:35 a. m.
, someone used a pay phone to call Heather. Police believe that call came from Tammy Moore. At 1:44 a.
m. , Heather called Briana crying. At 3:17 a.
m. , Heather called Sydney’s cell phone. After that call, Heather left her apartment and drove to the Peach Tree Landing, a desolate, dark area popular with fishermen and kayakers.
Her cell phone pinged there at 3:38 a. m. She made several more attempts to call Sydney, but her last live call was at 3:41 a.
m. After that, her phone went dead.
Less than 24 hours later, police received a call about a suspicious vehicle parked oddly at Peach Tree Landing. It was Heather’s car, registered to her father. Terry Elvis arrived with spare keys and opened the vehicle.
Inside, police found receipts timestamped earlier that day, but Heather’s purse, keys, and cell phone were gone. Terry tried calling his daughter over and over, but every call went straight to voicemail.
Police immediately focused on Sydney Moore as the last person Heather called or texted. Terry Elvis, desperate for answers, called Sydney himself. Sydney answered, cursing and denying he ever knew Heather.
He hung up when Terry pleaded for help. During initial questioning by police, Sydney claimed he had not spoken to Heather in at least two months, but phone records proved that was a lie. He later admitted he did speak to Heather that night, but only to tell her to stop calling him.
The investigation soon turned to Sydney and Tammy Moore. Tammy had made chilling social media posts, including one that read, “Well, Sydney cheated on me in the months of September, October with a psycho [expletive] who has since went missing.” Tammy also claimed she had been having Sydney followed since January 2012, warning Heather in a text, “It’s best you call back and speak to me.
Save yourself.”
The case exploded on social media, with tens of thousands on a “Find Heather Elvis” Facebook page demanding answers. But the online conversation quickly turned toxic. Trolls hurled accusations against Heather, her family, and her friends, while others defended the Moores.
Briana said she was called a liar and accused of fabricating text messages and phone calls. The social media maelstrom, she said, dragged her through the mud and became a distraction from the search for Heather.
The bizarre twists kept coming. A little more than a month after Heather vanished, police arrested two men who had inserted themselves into the investigation. One was Bill Barrett, a friend of Heather’s father who had organized fundraisers and searches.
Police accused him of conducting his own parallel investigation that interfered with their work. The other was Garrett Starns, a Myrtle Beach resident who fabricated misleading evidence and sent it to law enforcement. Both were charged with obstruction of justice.
Starn’s case was later dismissed, but Barrett’s case remains pending.
Just when it seemed the case could not get stranger, Heather’s father, Terry, filed a police report saying two men in a jeep approached him as he left work and yelled, “We already have Heather. Morgan is next,” referring to Terry’s other daughter. That threat case remains active.
Then, Sydney Moore reported that someone fired shots at him while he was driving with his family, and weeks later, he claimed he saw two men with a shotgun approach his vehicle near his home.
Police executed a search warrant at the Moore residence in what authorities described as “shock and awe.” Dozens of police cars swarmed the home, seizing property including guns and DVDs. Sydney and Tammy were arrested and charged with obstruction of justice.
Then came the stunner: they were also charged with two counts of indecent exposure. Their attorney later revealed that the charge stemmed from the Moores’ alibi: they claimed they were having 𝒔𝒆𝒙 in their truck at the time Heather disappeared.
Days later, prosecutors upgraded the charges to kidnapping and murder of Heather Elvis. The Moores were held without bond for months before a judge released them on $100,000 bond each, with GPS monitoring and a requirement to stay at least five miles away from Heather’s family. In another twist, the judge later allowed the Moores to move from South Carolina to Florida so Sydney could seek work, enraging Heather’s family.
“I was beyond outraged,” Terry Elvis said. “You have to live every day without your daughter. So why should they get rewarded?”
The prosecution’s case against the Moores is entirely circumstantial. They have no body, no direct evidence of murder, but they have a mountain of threatening texts from Tammy to Heather. One text read, “Someone’s about to get their beat down.
Your is about to take his last breath. You can tell me where you are right now or I will find out another way. That way won’t have a great turnout for you.”
Police also have surveillance footage showing a dark-colored truck traveling from the direction of the Moores’ house toward Peach Tree Landing around 3:36 a. m. , and then heading back around 3:46 a.
m. , right around the time Heather’s phone went dead.
The defense argues that countless black trucks could have been on that road and that the evidence is too weak to prove murder. “Just because you can’t find a body doesn’t mean the person hasn’t been murdered,” prosecutors counter. The case has been delayed multiple times, and the trial has not yet begun.
Heather’s family remains in a state of limbo, desperate for answers and justice. “We’ll never give up,” Terry Elvis said. “We’ll never stop searching.
We’ll never stop looking. We’ll never stop asking questions.”
As the months turn into years, the mystery of what happened to Heather Elvis continues to haunt Myrtle Beach. The community that once rallied to find her now waits in agonizing silence. The dark love triangle, the late-night phone calls, the abandoned car at a lonely boat landing — all of it paints a picture of a young woman caught in a web of passion and fury.
And somewhere out there, either in the cold waters of the Pee Dee River or in the ashes of a hidden fire, the truth lies buried. The only certainty is that a family is broken, a community is shattered, and two accused killers roam free while the search for Heather Elvis remains unfinished.
