Michael McClain, 29, of Manchester, New Hampshire, vanished in the early hours of April 21, 2019, after a night out at the Tropical Lounge in Nashua. Friends say an altercation in the nightclub parking lot prompted McClain to try to de-escalate, after which he became separated from the group. Surveillance places him near a McDonald’s and a parking garage at Riverfront Landing by the Merrimack River around 3:30 a.m., but he was not seen again.

More than one. There has been no activity on his phone, social media or credit cards since that night. Family searches of the area have turned up no concrete leads; some have speculated about a river drowning but no body has been recovered and his family, who say he was a strong swimmer, question that theory. McClain was known for work with autistic children through Easterseals New Hampshire and was described as responsible and caring.

Does anyone who was in Nashua that night, or who recognizes the surveillance locations around Riverfront Landing, have information that could help clarify what happened to Michael?
