Summary based on the NamUs case record (MP26434) and 8 other sources
Derek Adam Seehausen, a 26-year-old medical student at the University of Southern California (USC), was last seen on August 5, 2014, in Los Angeles, California. He was spotted walking on Alvarado Street around midnight after withdrawing $200 from an ATM and purchasing groceries earlier in the evening. Derek was described as 6 feet tall, weighing 180 pounds, with brown hair and hazel eyes. He was wearing a maroon shirt, tan shorts, and bright-colored sneakers.

After he was reported missing, his apartment was found undisturbed, with his keys, wallet, and phone left behind. There were a few unconfirmed sightings of Derek in the weeks following his disappearance, including on a Metro bus and along the Pacific Coast Highway. Despite these leads, his case remains unsolved, and his family continues to search for answers. Derek's disappearance raised concerns, as he was known for being punctual and dedicated to his studies in anesthesiology, with no prior history of mental illness or personal issues.
