Matthew Patrick Artesani, a 60-year-old white man, was last known to be in San Diego, California, on July 1, 2023. He is described as slender, about 5 feet 10 inches tall, approximately 150 pounds, with brown eyes and balding brown hair. Family contact continued during 2023 and he frequently traveled between San Diego and Mexico, a pattern described as normal for him. Communication stopped at some point after his last verified contact, and his disappearance was reported to police.

The San Diego Police Department’s Missing Persons Unit is handling the investigation and his case has been entered into the National Missing and Unidentified Persons System (NamUs). Family members later received unconfirmed rumors that he and his girlfriend, referred to as Francessca, may have been killed in Tijuana around August 2024; those accounts are described as rumors rather than confirmed findings. Anyone with information about Matthew’s movements in mid‑2023, his travel between the U.S. and Mexico, or sightings after July 1, 2023, is asked to come forward.
