Authorities in Indiana have spent the last two weeks searching for Bryson Muir, the missing 14-year-old son of former Indianapolis Colts defensive tackle Daniel Muir.

Indiana State Police issued a Silver Alert Friday for Bryson, who was last seen by relatives on June 16, with his mom driving him away from his grandmother’s Ohio home.

Within minutes of Bryson’s mother driving off, though, Indiana State Police said her vehicle was stopped by local cops, who said the boy was nowhere to be found.

Authorities recently launched an investigation into the teen’s parents, Daniel and Kristin Muir, after his grandmother provided officials with a photograph allegedly showing the boy’s eye blackened and swollen.
