Maisel’s family, from Fairfield, Connecticut, has joined the search in Rochester.

“We don’t know where Max is, and that’s very hard to deal with,” said Max Maisel’s father, Ivan Maisel. “We have a lot more questions than we do answers.”

Max Maisel’s sister, Elizabeth Maisel, was tearful as she talked to officers.

“It’s really hard not knowing where he is, and we just want him to come back,” she said.

Family members said they were not aware of anyone who would want to hurt Max, and said he does not have a history of mental illness.

Speaking to CBS affiliate WROC-TV, Rochester, Ivan Maisel said his son was quiet and a fan of movies and Broadway plays, anime and photography.
