A former editor on the Attack On Titan series has been arrested for the murder of his wife. Comicbook writes that Jung-hyun Park was taken into custody by authorities for the murder of his wife who died back in August. Park is accused of strangling his wife to death as well as lying to authorities and claiming his wife's death was a suicide.
Park was present for the beginning of Attack On Titan, and served as an editor-in-chief of Bessatsu Shonen Magazine, which featured the Manga's launch. While his go-ahead to launch the series was likely a part of the success it would have, he had no part in the creative process of the show.
I write that because I'm seeing a lot of other people questioning how this arrest will affect the show. It won't in any way, so rest assured that season two of the series is still on track as far as we know.
