Details of Disappearance

Seehausen was last seen by a friend in Glendale, California at 9:00 p.m. on August 5, 2014. He had spent the evening with friends, then left them, saying he had to get up early the next morning for work. He withdrew $200 in cash from an ATM in Los Angeles at approximately 10:30 p.m. It's unusual of him to carry that much cash. After using the ATM, he went to a supermarket and bought milk and cereal.

At 11:54 p.m. he used his smart phone to make a payment to a friend for $2,999. The friend had loaned him the money for school tuition, and Seehausen wasn't supposed to pay him back until after he graduated. He was last seen at 12:02 a.m. on August 6, walking northbound on Alvarado Street. This is the last sign of him. The friend he'd repaid texted him later in the morning to ask why he'd repaid the debt early, but Seehausen didn't respond.

When he missed his medical school classes later in the week, his friends contacted his parents in Pennsylvania, who called the police after they were unable to get in touch with him. Police went to his apartment and found no indication of foul play; it appeared he'd simply left.

His keys, phone, wallet and laptop computer were still inside the apartment, but his state identification  card wasn't in his wallet, and neither was the cash he'd withdrawn from the ATM. The milk and cereal he'd purchased on the night of her disappearance were also in the apartment. The cereal box had been opened but the milk hadn't been.

At the time of his disappearance, Seehausen was in his fourth year as a student at the University of Southern California's medical school. He was an excellent student and had decided to specialize in the field of anesthesiology. In his free time he liked outdoor pursuits such as hiking, surfing and scuba diving. He wasn't carrying his passport at the time of his disappearance, and there's no evidence he was involved with drugs.

According to his family, Seehausen had no prior history of mental illness or trouble in his life and had not given any indication that he was unhappy with his life. Investigators are not sure what happened to him and his case remains unsolved.
