One of the two weapons used was .40 caliber.
Police went to all the FFLs in the area and requested information on anyone who had purchased a .40-cal. pistol. They obtained the names of more than 60 purchasers.
Police then sent letters requesting that the pistol owners submit their weapons for voluntary ballistic testing.
About 40 complied. Five had sold their pistols and provided the buyers' names.
Police will investigate the 15 owners who did not respond to the initial letter.

I don't understand. If you don't have something to hide, what are you afraid of?
