On January 2, 1999, 11-year-old Mikelle Diane Biggs was last seen outside her family’s home in Mesa, Arizona, as daylight faded. Mikelle and her nine-year-old sister Kimber had been with other neighborhood children waiting for an ice cream truck. Kimber left briefly to go toward the house because she was cold; when she returned she found Mikelle’s bicycle in the roadway near Toltec Street and El Moro Avenue, one wheel still turning, and two quarters on the ground. Mikelle herself was nowhere to be seen.

Investigators concluded the window for her disappearance may have been about 90 seconds. There were no reported witnesses who saw a forced abduction or heard a cry for help. Police and volunteers searched the area, and detectives later examined neighbors and registered sex offenders in the vicinity.

Mikelle is described as about 4 feet 8 inches, with brown hair and hazel eyes; she was wearing a red shirt with a white stripe and blue jeans with designs. The family has worked to keep her memory alive and the case remains open. If anyone was in the Toltec and El Moro area on January 2, 1999, or has information about the bicycle, the two quarters, or the one-dollar bill tip, can you help?
