A good guy with a gun stopped the Texas church shooter — now hear what one of the heroes has to say

If it weren't for a good guy with a gun, more lives could have been lost Sunday when a gunman opened fire in a small church in Texas.

What happened?

According to law enforcement officials, a local Sutherland Springs, Texas, resident confronted 26-year-old Devin Patrick Kelley after he opened fire on parishioners in the town's First Baptist Church.

CNN reports that when Kelly opened fire on the church with a semi-automatic AR-15 rifle, a local resident grabbed his own rifle and engaged Kelly, causing him to stop firing on the church, get into a vehicle and run. From there, a chase ensued and Kelly ended up dead. It's not clear if the resident shot Kelly or if he died from a self-inflicted gunshot.

The resident who engaged Kelly ran into a man's truck to chase him. That man, Johnnie Langendorff, told his story to local news stations.

What did Langendorff say?

Langendorff told local news station KSAT-TV that he saw the unnamed resident engaging in fire with Kelly. That's when the resident ran to his truck and they began chasing Kelly. All the while, they were communicating with dispatchers.

Langendorff said the chase reached speeds of up to 95 mph before Kelly lost control of his vehicle and crashed. Langendorff said the unnamed resident then held Kelly at gunpoint. Sometime after the crash is when Kelly died, though it's not clear when.

"[I was] just trying to get him, to get him apprehended or whatever needed to happened. I mean it was just strictly acting on what the right thing to do was," Langendorff said.

According to Fox News, the latest updates says that 26 people lost their lives in the church. Dozens of others were injured.

Authorities say the two men saved "countless" lives.
