Missing Suicidal Teen Leaves Lakeside Hospital Against Medical Advice

Summary: A 17-year-old white male, Thomas Mertz, left Lakeside Hospital ER in Omaha, Nebraska, against medical advice. He was last seen wearing a dark blue button-down shirt, blue jeans, and black shoes, carrying a white plastic bag. The hospital reported he was confused and had been making threats to harm himself. Police were attempting to obtain a mental health hold (BMH) for him. He is known to sometimes carry a gun in his vehicle, though no weapon was reported on his person. Officers later checked his well-being at 15669 Fountain Hills Drive but did not locate him. The situation is considered high risk due to his mental state and potential access to a firearm.
