Aaron Alexis Bought Shotgun Sunday

As D.C. recovers from the Navy Yard shooting that left 12 dead, investigators are zeroing in on the suspected gunman, Aaron Alexis. According to officials, the 34-year-old purchased a Remington 870 shotgun and two boxes of shells on Sunday, after passing both state and federal background checks. A lawyer for SharpShooters Small Arms Range confirmed that Alexis’s background check was approved prior to the sale. Previous to Sunday’s transaction, Alexis rented a rifle at SharpShooters and practiced at their shooting range. Earlier in the day Tuesday, investigators revealed that Alexis suffered from PTSD.
