Felix DeJesus’ family is holding onto hopes of finding him alive two years after police in Paterson, New Jersey dropped him off in a city park, inebriated and wearing a T-shirt as temperatures dropped below freezing.

“We keep going around the spots, asking people questions, but nothing has come up yet,” his brother Giovanni DeJesus said. But maintaining that hope has been a struggle amid a lack of signs of DeJesus’ possible whereabouts — or whether he’s still alive.
