Photos and videos from a Facebook page apparently belonging to Brian Isaack Clyde, the 22-year-old man identified by federal officials as the person who shot up downtown Dallas' Earle Cabell federal courthouse Monday, show the suspected shooter handling a rifle that looks similar to the one with which he was photographed Monday, bragging about owning high-capacity magazines and struggling to hold on to reality.
Clyde's Facebook page includes several photos in which a distinctive heart-shaped tattoo is visible on his left arm. The tattoo matches one described by The Dallas Morning News as having appeared in a photo of the suspected gunman.
Clyde died after a short shootout with federal law enforcement agents outside the courthouse.
In a video posted last week, Clyde shows off his rifle during a rain storm.
On his page, Clyde also expressed anti-federal government rhetoric and a love for gun shows.
Other posts reflect Clyde's mental health struggles.
