(Witness ID #00112)Brian █████ was an actor in the production of Marble Hornets and a good friend of Alex Kralie. He has been known to associate with Tim ██████, Seth █████████ and Sarah ███████ as well. His role in the Marble Hornets case is uncertain other than a witness.
His first appearance in the Marble Hornets case was in the footage Jay ██████ posted in Entry #7 , where he is reading his lines to Alex Kralie. He does not see the Slender Man in the background as Alex Kralie did.
Brian █████'s house was used as a location for the Marble Hornets film, as seen in Entry #20 . It is speculated that the house that Jay ██████ was given the tip for was Brian █████'s. Jay ██████ makes several visits to the house, breaking in each time as it seemed to have been abandoned. These entries include:
Entry #16 
Entry #18 
Entry #23 
Entry #18 is the first encounter with the Masky suspect. He also encounters him again in Entry #23. Also in Entry #23, Jay ██████ and the camera black out several times and awake initially in the first floor closet, then in the ruined building from Entry #22 .
At the end of the footage in Entry #22, Alex Kralie wakes up in the house and reveals that Brian █████ has gone missing along with the rest of the cast, listing the names of Tim ██████, Seth █████████, Sarah ███████, Brian █████, and even Jay ██████. It is assumed that Brian █████ met the same fate as Seth █████████ and Sarah ███████, as the others are more or less accounted for.
