Summary based on the NamUs case record (MP24405) and 9 other sources
Lucas "Luke" Arduini, a 27-year-old software programmer from Oakland, California, went missing on January 1, 2014, after attending a New Year's Eve party in San Francisco. He was last seen between 4:00 and 5:30 p.m. on New Year's Day near the Bay Bridge, reportedly wearing a purple hooded sweatshirt and red Converse sneakers. Luke had taken an Uber from the party back to his apartment in Oakland earlier that morning, and there is evidence suggesting he made it home, though where he went afterward remains unknown.

Luke's sudden disappearance was alarming to his family and friends, particularly since he left behind important personal items like his insulin, suggesting he may have been in need of medical attention. Despite extensive efforts by friends, family, and a private investigator hired by his employer, Yahoo, no concrete leads have emerged. His case remains open, and authorities continue to investigate.

Luke was known for his intellect and had several distinctive tattoos, including a Linux code on his chest and the number "42" on his throat. Friends described him as a deep thinker, but his disappearance has left many questions unanswered. Anyone with information about his whereabouts is encouraged to contact the Oakland Police Department.
