I think the most alarming thing about this tweet is how many times it was retweeted and how many "likes" it got. BT was certainly not the only one responding to it. Scary to me ..The deleted BT tweets are shown in this article:
On July 19 at 11:14 p.m., minutes before the crime was allegedly committed, Theesfeld liked a tweet from the account @CauseWereGuys. The tweet included two photos: one was a screen-grab of the video game “Call of Duty,” looking through the scope of a rifle, and the other was of a woman sitting in front of a window.
According to multiple reports, Kostial was last seen sometime after midnight on July 19.
