Missing person: tall man in red hoodie

I lost my brother, Mateo Rivera, yesterday around 7:15 pm. He's about 28 years old, 5'11", lean build, with short dark hair and light stubble. He was last seen wearing a black leather jacket over a red hoodie, blue jeans, and gray sneakers. He has a compass tattoo on his left wrist and a small scar above his right eyebrow. We were near the Hartford Public Library on Main Street as dusk fell, and he wandered toward Bushnell Park; I haven't heard from him since. I'm really worried—he has a medical condition and needs his meds; if you see him, contact me immediately.
