This is taking place at Walter Reed Medical Center.

137, the 33rd prime; False Flag = 33; Police = 33; Masonry = 33; Secrecy = 33; Order = 33

The name Walter Reed Medical Military Center also sums to 330, not unlike 33.

As for the word 'military', you know how that connects to shooting.  Keep in mind this is a hospital as well...

The location is in Bethesda.

Bethesda is in Maryland, and this news comes on the day leaving 34-days left in the year.
