Michał Marcin Krówczyński, a 30-year-old math teacher from Kraków, Poland, was last seen January 17, 2019, in San Diego, California. He was on vacation in the U.S. and planned to fly to Phoenix on January 18 but never boarded that flight and has not been heard from since.

His last known location was near Bird Rock in La Jolla, where he posted a photo on social media shortly before disappearing. There are concerns he may have had an accident in the rocky coastal area, possibly falling into a crevice or becoming incapacitated. Friends and family in both the U.S. and Poland have asked local residents to search around Bird Rock for him or for belongings such as a phone or backpack.

The San Diego Police Department is leading the investigation, and despite search efforts no substantial clues have emerged. If anyone was in the Bird Rock area on January 17, 2019, or has information about Michał’s movements or possible sightings, please share what you know.
