I live in the area, and have been following local and national reports on this.
The Houston homicide / special investigations guy just said that from all investigation and discussions with people, the shooter is a female. Ummmm, how about just confirm with an autopsy? He also stated that on the stock of the AR-15 was the word Palestine, no "Free." The shooter also had a .22 rifle. Finally, the investigator said that there might be a possible beef with her ex-husband and his damily, since they're Jewish and anti-Semitic writings were found.
Interesting how this happens just as Congress is balking on providing Israel with USD 18,000,000,000.00.
Two off-duty LEOs, one a Houston PD or deputy, the other a TABC Police officer, took out the shooter within seconds of the shooter opening fire. Short phone videos from people inside the $megachurch$ on the interwebs show this.
