Authorities investigating the church massacre in Sutherland Springs said Tuesday that they have the cell phone of shooter Devin Kelley but haven't been able to access its contents.

Chris Combs, special agent in charge of the FBI in San Antonio, said the phone was flown last night by DPS plane to FBI headquarters in Quantico, Virginia, to see if experts there can break into it.

“Unfortunately at this time, we're unable to get into that phone,” Combs said. “So it actually highlights an issue that you've all heard about before, and the advance of the technology and these phones and the encryption. Law enforcement…is increasingly not able to get into these phones.”

Investigators said they obtained a search warrant to get into it and “other digital media” but wouldn’t get into specifics.

Meanwhile, the Texas Department of Public Safety won’t say why Kelley was denied a concealed gun license, saying it's “protected information” but that they had no information precluding Kelley from buying a gun.

Also, investigators said there is no evidence a bump stock was used on the AR-556 rifle. The assault-style rifle was tested by the Bureau of Alcohol, Tobacco and Firearms and those preliminary tests show it is semi-automatic and not fully automatic, said Fred Milanowski, special agent of ATF in Houston, which covers Sutherland Springs and San Antonio.
