Yes, I'm under the impression the last tweet could be directed to male/female; however, after reading the latest update, I think it is male. Also, I do not believe she was referring to followers on twitters, I believe she meant physically being followed, do to a) the time stamp of the tweet just after 1 AM and b) the approximate GPS coordinates of the tweet, which was roughly .3 miles from the wooded area.
Also, I believe there to be more than one suspect, due to her plural description of b*****s noted in her last tweet. Just my beliefs of course, hopefully we get official word and arrests made sooner than later.
Here is the map I have made...if you click on the pin points starting with pinpoint A at roughly 5PM, I put the tweets she had in there as well.
