Many fans were excited to hear that "Longmire" Season 5 is only a couple of months away from its release on Netflix. Inquisitr noted that a September release date for the upcoming season is expected because the cast and crew should be done filming in June.

The speculated "Longmire" Season 5 release date in September also seemed plausible because the previous season of the show also premiered in the same month. The upcoming season of the show is also expected to be a continuation of the events from Season 4, which ended with a cliffhanger.

"Longmire" Season 5 spoilers also debate on the possible suspects behind the mystery intruder who broke into Walt's house. Walt and Dr. Donna Sue Monaghan were sharing an intimate moment when this happened, Master Herald reported.

Many fans are speculating that the mystery intruder, who will be unveiled in "Longmire" Season 5, is none other than Walker Browning, especially because he and Walt have always had something against each other. Others are also speculating that Walker and Donna are working together, which may also pave the way for the romantic relationship between Walt and Vic.
