Tyler Joseph Schladweiler was three years old when he was last seen in Lake Havasu City, Arizona, on October 9, 2002, in the company of his non-custodial mother, Melissa Schladweiler. Tyler was described as White, with light brown hair and brown eyes, about 2 feet 9 inches tall and 30 pounds, with scars on his abdomen and knee. Authorities treat this as a family abduction.

A felony warrant for Melissa Schladweiler was issued on October 7, 2003. Melissa was described at the time as a 39-year-old White female, brown hair, blue eyes, 5 feet 9 inches tall and 160 pounds. The Lake Havasu City Police Department, working with the National Center for Missing & Exploited Children, released age-progressed images of Tyler in later years.

Anyone who knew Tyler, Melissa, or has information about their locations is asked to contact the Lake Havasu City Police Department.
