MOD EDIT - Article intro pulled for context:

"Former Michigan linebacker Elysee Mbem-Bosse sent out a series of potentially threatening tweets on Monday night. At the end of one thread, Mbem-Bosse lamented that he was suspended for “going to take care of my family” and tagged head coach Jim Harbaugh in the comments.

Reddit user cappy412 captured screenshots of Mbem-Bosse’s tweets in which he hinted at a “murder case” and repeated that Michigan was “open carry.”
