Kristopher Blankenheim was 31 when he was last seen in Santa Rosa, California, on December 1, 2021. He had a history of substance abuse and repeated legal troubles, including arrests for drug possession and probation violations, which family members say may have increased his vulnerability before he disappeared. No specific details were released about where he was headed or his mental state on the day he vanished. The Santa Rosa Police Department and relatives have pursued leads but report no major breakthroughs; he remains an active missing person.

If anyone has information about Kristopher’s whereabouts or saw him around December 1, please contact the Santa Rosa Police Department.
