IMO JW shot CR Sr. in the forearm with the SKS .30 Cal rifle (long gun) from outside the trailer, BW shot CR Sr., GR and KR with the .40 (caliber) Glock (brand) handgun with Hornaday (brand) hollow point bullets, JW shot FR, HHG, DR, HMR and CR Jr. with the .22 (caliber) Colt 1911 LR (brand) handgun with Remington (brand) bullets. LR stands for long rifle, it is the type of bullet, it is longer than a standard .22 bullet (has more gunpowder). Evidence photos below, sorry, don't have photos of .40 Cal Glock handgun or .30 Cal SKS rifle yet! And it has not been stated what brand of bullets came out of the .30 rifle. HTH!
