On December 13, 2021, at approximately 6:15 a.m., officers were contacted after a 5-year-old girl was reported missing from a home at 1607 Bowman Street in Columbus, Georgia. Later that night, investigators searching a vacant home in the 1100 block of 15th Avenue in Phenix City, Alabama, found the child deceased beneath a tarp in the basement. She was pronounced dead at approximately 11:15 p.m. The victim was identified as 5-year-old Kamarie Holland. At the time, Kamarie's father had sole legal custody of her. Her mother, Kristy Marie Siple, had previously lost custody because of substance abuse issues, and a juvenile court had a no-contact order in place between Siple and Kamarie. Kamarie's father had nevertheless left her in Siple's care. During the investigation into Kamarie's disappearance, detectives began looking for then-37-year-old Jeremy Tremaine Williams, who was among the last people seen with her. Investigators also learned that several days earlier, an adult woman had accused Williams of forcibly sexually assaulting her. The woman told police Williams had made disturbing statements about sexually abusing a 5-year-old girl. Police obtained a warrant to search Williams' property in Columbus. Inside a shed behind the home, investigators found a child-sized foam chair and a peanut-butter sandwich with what appeared to be a child-sized bite taken from it. Williams' wife arrived during the search and gave investigators the address of a duplex in Phenix City where she believed Kamarie could be found if Williams had harmed her. Around the same time, authorities located Williams at a motel in Phenix City and took him into custody. Electronic devices and drug paraphernalia were recovered from his room. Investigators then went to the Phenix City duplex. In the basement, they found Kamarie's nude body beneath a tarp. Investigators observed ligature marks around her wrists and neck, bruising to her face and evidence of severe sexual assault. An autopsy determined Kamarie died from asphyxia. Several weeks later, on Christmas night, Williams asked jail staff to speak with investigators, saying he wanted to discuss similar crimes and get them off his chest. During that interview, Williams admitted sexually abusing his own daughter while the family lived in Alaska and said the abuse continued after they moved to Texas. He also admitted molesting other young girls. When investigators questioned Williams about Kamarie, he admitted killing her. Williams said he knew Siple through a prostitution website and that the two had a sexual relationship and used methamphetamine together. According to Williams, Siple had previously left her children in his care despite him having told her he was sexually attracted to young children. Williams admitted negotiating with Siple for access to Kamarie. The two eventually agreed that Williams would pay $2,500 to take the 5-year-old for approximately one hour and sexually abuse her. Williams later admitted that he never had the money and never intended to pay Siple. At approximately 2 a.m. on December 13, Williams took Kamarie from Siple's home and brought her to his residence in Columbus. Williams' wife later saw him with Kamarie and told him he could not remain there with the child. At approximately 6:20 a.m., Williams left with Kamarie and drove her to the Phenix City duplex. During the drive, Williams showed Kamarie pornography. He later admitted that when the 5-year-old refused to perform what she was being shown, he punched her in the head. At the duplex, Williams deliberately parked his vehicle where his aunt, who lived across the street, would not see that he was there. Williams again showed Kamarie pornography. He also smoked methamphetamine and made the child smoke the drug. Williams admitted subjecting Kamarie to multiple forms of sexual assault for approximately an hour to an hour and a half. He later told investigators that he became concerned he would be caught because he had gone beyond the sexual act he and Siple had agreed upon. Williams then strangled Kamarie. According to Williams' own account, it took approximately 10 to 15 minutes for Kamarie to die. At one point, Williams believed she was dead and released his grip because his hands were tired. Kamarie sat up and gasped for air. Williams admitted that he then began strangling her again until she died. Williams used his cellphone to photograph and record his sexual abuse of Kamarie both before and after her death. Investigators later recovered those photographs and videos from his phone. On December 28, 2021, Siple was arrested in connection with her daughter's death. On March 13, 2024, Siple pleaded guilty to first-degree human trafficking after prosecutors agreed to dismiss the murder charges against her. She agreed to a 20-year prison sentence and to testify against Williams if necessary. She was also required to register as a sex offender. That same day, Williams entered guilty pleas to four counts of capital murder and several additional offenses. His plea was entered without an agreement with prosecutors. When the judge asked why he wanted to plead guilty, Williams said he wanted to expedite the process. Because Alabama law requires the state to prove a defendant's guilt to a jury when seeking the death penalty, Williams still went to trial on the capital murder charges despite his guilty pleas. On April 12, 2024, after approximately 90 minutes of deliberations, a jury found Williams guilty of four counts of capital murder: killing a child younger than 14, murder during a kidnapping, murder during a rape and murder during first-degree sodomy. Williams waived the jury's participation in determining his punishment and declined to present mitigating evidence. On April 15, 2024, a judge sentenced him to death on all four capital murder convictions. Williams was also sentenced to life in prison for production of obscene material involving a child, life for human trafficking, 20 years for conspiracy to commit human trafficking and 10 years for abuse of a corpse. Beginning in early 2025, Williams sent a series of letters to the Alabama Attorney General's Office saying he wanted to abandon further appeals and have an execution date set. Because death sentences receive mandatory appellate review in Alabama, Williams could not simply end the process immediately. During a May 23, 2025 hearing, a judge questioned Williams extensively about his decision to represent himself and stop pursuing appellate issues. Williams said he understood that doing so would cause him to be executed sooner. The court determined his decision was knowing and voluntary. On March 27, 2026, the Alabama Court of Criminal Appeals upheld all four capital murder convictions and Williams' death sentence. Williams continued asking for his execution to proceed, writing that he wanted Kamarie's family to receive whatever closure and satisfaction his execution could provide. On June 16, 2026, the Alabama Supreme Court authorized the state to carry out Williams' death sentence. Two days later, Gov. Kay Ivey established a 30-hour execution window beginning August 13 and ending at 6 a.m. August 14. On August 13, 2026, 42-year-old Jeremy Williams was executed by lethal injection in Alabama. He was pronounced dead at 6:16 p.m. CDT. In his final statement, Williams said, "I want to thank God for forgiving me for my sins so I can meet him in peace." Kamarie's father has described his daughter as an energetic little girl who loved princesses, dressing up and making people laugh.
