Mikelle was last seen riding her bicycle near her family's residence in Mesa, Arizona on January 2, 1999. Mikelle and her younger sister thought they heard an ice cream truck's music in the distance and asked their mother for money. Mikelle and her sister waited for the truck near Toltec Street and El Moro Avenue at approximately 5:50 p.m. Her sister became cold and returned to the family's home for a coat. Their mother sent her back for Mikelle, but she had disappeared. Mikelle's bicycle and her two quarters were found near the street where she had been standing. It was lying on its side with the wheel still spinning. Authorities searched the entire area near Mikelle's family's home, but no evidence pertaining to her whereabouts was found. Search dogs lost her scent after only a few feet, suggesting she was placed into a vehicle and driven away. There are few leads in Mikelle's disappearance and her case remains unsolved. She would be 37-years-old.
