SUTHERLAND SPRINGS, Texas — Investigators said in a press conference Monday evening that the autopsy of the Sutherland Springs shooter is now complete and an intense investigation is still underway. 

"I can tell you the scene in there...horrific is not even a word to describe it," said FBI Special Agent in Charge Christopher Combs. 

Those are the words of the FBI describing a The First Baptist Church. The bodies of more than two dozen victims removed from the scene — what DPS is calling a "substantial amount" of evidence is now collected.

"Including hundreds of shell casings, more than 15 magazines, 30 round magazines were recovered,” said Freeman Martin of DPS. 

Also now in evidence, the suspect's getaway vehicle. An autopsy conducted Monday morning showed three gunshot wounds — one in the leg and one in the torso in the gunman's body. That's consistent with the story of the armed neighbor who shot at the suspect. The third — a gunshot to the head that the medical examiner described as self inflicted.

But questions are swirling over where the suspect got those high-powered weapons.

There are now a few more answers there too.

"I can tell you for the four purchases he made, the NIX system did the required check and there was no prohibited information in the system that said he could not purchase the guns," said Combs. 

The shooter was court martialed for attacking his now ex-wife and her child.

He served time, but the Air Force admitted it didn't enter the shooter's criminal history into a FBI background check database allowing him the opportunity to purchase those guns.

As the investigation continues, there were these words from authorities.

"We'd like to ask you to please keep these victims and their families in your thoughts and prayers. They're very much welcome and very much needed,” said Martin.
