Jose DeJesus pulls his silver minivan out of a parking lot in back of a row of historic houses on New Haven’s Congress Avenue. He points with pride to the flowers he planted around the lot. Then he grimly spins a commentary as he gives a tour of the surrounding Hill neighborhood. • There’s the John C. Daniels School, where parents are dropping off kids and where a man overdosed and died near a rear stairwell over the summer. • Across the street, there’s the APT Foundation clinic, where clients in recovery from opioid use come every morning for methadone.
