The gunman, who police say is now dead, opened fire at the Sutherland Springs First Baptist Church around 11:30 Sunday morning. Wilson County Commissioner Albert Gamez Jr. estimates that at least 26 people were killed, which is roughly half of the average congregation at the 11 a.m. service. Witnesses say one of the victims is a 2-year-old child. According to CBS News, one of the deceased is the pastor's 14-year-old daughter.
The FBI, U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives and Texas Rangers have joined the Wilson County Sheriff's Office in investigating the case.
The shooting prompted several nearby churches to go on lockdown. It's unclear how many others were injured in the shooting, nor how many people were at the church at the time. At least nine of the injured people were taken to University Hospital in San Antonio. Four of them are children.
This is the 307th mass shooting in the United States in 2017.
Elected officials have already responded to the shooting on social media.
"While the details of this horrific act are still under investigation, Cecilia and I want to send our sincerest thoughts and prayers to all those who have been affected by this evil act," said Gov. Greg Abbott in a Twitter statement.
