Kadin McKallaster Black was 19 when he was last seen on December 17, 2022. He had been staying with a childhood friend and that family in East Prospect, Pennsylvania, and reportedly left with only his wallet and the clothes he was wearing. His phone last pinged a cell tower in the Lower Windsor Township/East Prospect area on the morning of December 18, 2022, then went silent.

In the months before he vanished Kadin attended an alternative school for students with social, emotional, or behavioral needs. His mother said he had diagnoses of bipolar disorder, high-functioning autism, and oppositional defiant disorder. He had been arrested in March 2022 after a confrontation with a school bus driver and was due in court in January 2023; family members say he feared going to jail, and that is considered a possible factor in his disappearance. Extensive searches by multiple agencies, including air, land, and water operations, have found no trace.

Does anyone who knew Kadin or saw him in East Prospect or Lower Windsor Township around December 17–18, 2022 have information to share with investigators?
