Michal Marcin Krowczynski was reported missing on Jan. 18 while on vacation in the United States from Poland.

Krowczynski failed to report to his scheduled flight to return home and family and friends have been unable to reach him since Jan. 17.

The man’s social media accounts showed various posts throughout the San Diego area before his disappearance, but has shown no activity since. He was reportedly last seen in the La Jolla area.

Krowczynski has never been reported missing before and the circumstances surrounding his disappearance are considered unusual. He is described as a white male, approximately 5 feet 9 inches tall, weighing 180 pounds, with brown hair and green eyes.

Any information related to the whereabouts of Krowczynski should be forwarded to San Diego Police Department at (619) 531-2000 or SDPD Missing Persons Unit (619) 531-2277.
