Three-year-old Mario Langer was last seen in Plano, Texas, on July 10, 2023. He is described as a Hispanic male with blondish hair and brown eyes, about 3 feet 2 inches tall and weighing roughly 30 pounds. The Plano Police Department is handling the investigation into his disappearance.

Mario’s vanishing came one day after 36-year-old Diuliane Langer was reported missing from the same city on July 9, 2023. Public information links the two cases by time and place, but details about their relationship and the circumstances of either disappearance are scarce. Official missing person registries continue to list Mario as missing.

If anyone has information about where Mario might be, or recalls seeing him in Plano around July 10, 2023, please share what is known with the authorities.
