Ephram Scott Richeson was two years old when he vanished from St. David, Arizona, on October 22, 2007. Described as biracial (White and Hispanic) with sandy brown hair, brown eyes, a small scar above his right eye and a birthmark on his abdomen, he was reported at 2 feet 7 inches and 31 pounds and was last seen wearing white Spiderman sneakers. He was in the care of his non-custodial father, Jonathan Scott Richeson, when he disappeared.

Investigators treated the case as a parental abduction. A felony kidnapping warrant for Jonathan was issued March 3, 2008. Jonathan was described then as a 37-year-old White male, 5 feet 7 inches and 170 pounds, with brown hair and brown eyes; both father and son are bilingual in English and Spanish. Authorities have suggested possible travel to Mexico, Ecuador or other parts of Central or South America, and age-progressed images have been released as the search continued.

The whereabouts of Ephram and Jonathan Richeson remain unknown. If anyone has information about their locations or saw them after October 22, 2007, please share what is known with investigators.
