Sims's mother, Dwanna Harris (who later married and changed her name to Dwanna Jackson), told authorities that her son disappeared while shopping with her at The Wonderland Mall in Livonia, Michigan on December 11, 1994. Harris stated that Sims was walking along the corridor between the Target store and the main area of the shopping mall with her when he suddenly vanished. Sims has never been heard from again.

Investigators administered two polygraph tests to Harris shortly after Sims disappeared. She failed both of the attempts. Authorities stated that they did not believe Harris's story and believed Sims was never at The Wonderland Mall with his mother the day he disappeared. No witnesses saw him there and he does not show up on the surveillance camera tapes.

Harris has maintained her innocence and said in 1995 that she was in therapy to deal with her son's disappearance. Relations between law enforcement and Harris have been strained due to their conflicting beliefs, but Harris told the media that she keeps in contact with all agencies regarding Sims's case. Harris has never been charged in connection with her son's disappearance due to lack of evidence, and no suspects have been identified. Her mother says Harris was emotionally devastated by her son's disappearance.

There have been numerous leads regarding Sims's whereabouts throughout the proceeding years, but all failed to produce any evidence. One possible lead came in 1999, when investigators received a tip from another law enforcement agency regarding Sims's fate. Authorities excavated an area in Hines Park in Dearborn Heights, Michigan and discovered a bag of bones buried at the location. DNA tests were performed on the evidence, and testing proved the bones were not Sims's remains.

In November 2003, the possibility was raised that Sims may be an unidentified child whose skeletal remains were found in Dekalb County, Georgia in 1999. The child is an African-American male approximately four feet tall. He was between five and seven years old when he died, and was wearing red denim jeans, new size 11 brown suede Timberland boots, and a long-sleeved hooded pullover shirt. The body of the shirt was blue plaid material and the sleeves and hood were dark blue thermal material. An artist's sketch of the child is posted below this case summary. DNA tests were conducted using DNA from Sims's parents, comparing them to the unidentified child's DNA. The testing ruled out the possibility that Sims was the boy. If you have information about the unidentified boy, call the Dekalb County Police at 404-294-2670.

Sims remains missing. At the time of his disappearance he enjoyed watching television, especially the Mighty Morphin Power Rangers show. His case remains open and unsolved.
