Missing man: tall, navy jacket, Lincoln downtown

I lost my brother, 25, in Lincoln yesterday around 3:30pm. He was last seen near the Lincoln City Market on Main Street, heading toward the old train depot. He's about 6 foot 1 inch tall, with short brown hair and a light beard, wearing a navy rain jacket with a red lining, a gray hoodie underneath, and black jeans. He has a silver compass tattoo on his right wrist and a small scar above his left eyebrow. I'm really worried—crowds get overwhelming for him, and it's unlike him to vanish like this. If you spot him, please contact me here; he sometimes responds to the nickname Marco if you call him by name.
