Angie Tucker, a resident of Tulsa, Oklahoma, disappeared on November 3, 2007, at around 11:30 p.m. She was residing with her mother, along with her two children, on Apache Street and Yale Avenue. Tucker informed her mother that she was going out to purchase cigarettes, but she never returned home. She has not been heard from since, and authorities have reason to believe that foul play may be involved in her disappearance.

Tucker was described as a dedicated mother and reliable employee, and it was unlike her to leave without warning. She did not own a vehicle at the time of her disappearance. A month before her disappearance, Tucker accused her former boyfriend, Allen Shields, of raping her. Shields was arrested on charges of burglary and rape, but he was released on the same day after posting bail. Tucker obtained a restraining order against Shields, and he was scheduled to appear in court for the charges she brought against him. However, Tucker vanished before she had the opportunity to testify against him, and the charges were dropped due to insufficient evidence.

Shields is a person of interest in Tucker's disappearance. Although he denies any involvement in her disappearance, he is not entirely out of the picture. Shields was charged with several felonies, including kidnapping, assault, and burglary, in an unrelated case in February 2010. Authorities found a "kidnap/murder kit" in his possession, containing a handgun, handcuffs, drugs, a mask, pepper spray, and disinfectant wipes. Shields broke into his ex-girlfriend's home and waited for up to thirteen hours for her and her daughter to return. He then attacked the woman, and the daughter alerted the authorities, preventing a possible murder.

Tucker's case received additional media attention when Shields was charged with an unrelated incident. Authorities found similarities between the cases. Both women had dated Shields, and the relationships had ended on sour terms. Both Tucker and the 2010 victim had filed protective orders against him.

In September 2008, a local businessman named Neal Sweeney was murdered, and Shields was charged with conspiracy to commit murder. Shields pleaded guilty to conspiracy and agreed to testify against four other defendants in October 2010. He received ten years of probation and was released from prison. In January 2011, police took a DNA sample from Shields in connection with the murder of Frederick Anthony Wilson, who was killed in a home invasion robbery in April 2008.

In April 2011, Shields committed suicide after holding his ex-girlfriend's daughter hostage in a standoff with the police. He failed to appear in court on the day of his death, and authorities received information that he was holding a child hostage. Investigators planned to continue investigating Tucker's disappearance after Shields' death.

Tucker worked at the Oklahoma State University Medical Center when she disappeared, and her children are currently in the custody of relatives. Her disappearance remains unsolved.
