Texas church shooting: How it happened
He was dressed in black "tactical-type gear" and wearing a ballistic vest, officials said.
He fired in front of the church, then moved to the right side of the building and kept shooting.
A man who lives next door to the church grabbed his own rifle and engaged the suspect, officials said. The gunman dropped his "Ruger AR assault-type rifle" and fled. The neighbor chased after the gunman, police said.
The chase ended when the shooter crashed his car about eight miles from the church.
Police don't know if the suspect died of a self-inflicted gunshot wound or if he was shot by resident who confronted him.
"We are dealing with the largest mass shooting in our state's history," Texas Gov. Greg Abbott said.
