Oscar Ramirez was 17 when he was last seen in Kansas City, Kansas, on September 1, 2019. He is described as a Hispanic male with black hair and brown eyes, about 5 feet 6 inches tall and 120 pounds. Very few concrete details have been released about his disappearance; there are no widely publicized descriptions of what he was wearing or who he might have been with that day.

Investigators have explored a lead that he may have traveled to Louisville, Kentucky, and there is a suggestion he might be using the alias last name Ramirezargueta.

Anyone who knew Oscar, saw him around Kansas City in late summer 2019, or has information about travel to Louisville or the Ramirezargueta name is asked to come forward.
