Church livestream video shows fatal Texas shooting

A man pulled out a shotgun at a Texas church service and fired on worshippers on Sunday, killing two people before he was shot to death by congregants who fired back, police said.

Authorities at a Sunday evening news conference praised the two congregants who opened fire as part of a volunteer security team at West Freeway Church of Christ in White Settlement.

It was unclear if the two people who were killed were the two who shot at the gunman.

“This team responded quickly and within six seconds, the shooting was over.

"Two of the parishioners who were volunteers of the security force drew their weapons and took out the killer immediately, saving untold number of lives," said Lieutenant Governor Dan Patrick.

White Settlement Police Department Chief JP Bevering said the gunman had sat down in a pew before getting up, taking out a shotgun and firing at a parishioner, who was killed.

He said the church's security team then “eliminated the threat.”

Officials have not released the names of the victims or the gunman.

In a livestream of the church service, the gunman can be seen getting up from a pew and talking to someone at the back of the church before pulling out a gun and opening fire.

Parishioners can then be heard screaming and seen ducking under pews or running as papers fly to the floor.
