A family has spent over 48 hours searching for a Bronx man who apparently got lost trying to take the 6 train home late Saturday night. The family of 63-year-old David Thompson says he was on his way back to East 138th Street when he told them he was not sure where he was and needed help. His wife sent a car for him on Sunday morning and they talked to him again, but he said he was still lost. That was the last time they say they heard from him, and his phone has now died. Since then, the family has been trying to spread information about him online, while also traveling around the city, following any clue. One possible cellphone ping took them to Rockaway Beach, but that ended up being wrong information, then someone on TikTok said they might have seen him near the Whole Foods in Harlem. Family members say he had been suffering from memory and balance issues lately and had an appointment scheduled with a neurologist to find out what was wrong. They believe he may have become disoriented, which is why they have also been going to anywhere that might be familiar to him, including places where he used to live and work. "We're hoping that he's looking for solid ground, and he's looking for the things that make him happy, the things that he remembers, we're hoping that he's doing normal things in an abnormal way - walking around, getting things to eat," said his sister, Patricia Thompson." I don't want to think about him not having shelter, especially on a hot day like this, but it's been hard, especially the last couple of days." The family says the flyers, which include the phone number of another one of his sisters are for Thompson to see as much as anyone else - so that if he sees one, he can show it and the number to another person on the street, and they can help get him help.
