Brianna Jimenez, a waitress at the restaurant, said she saw Albert walk in wearing a mask and sunglasses. She said as she rose to greet him, he motioned for her to sit back down and continued to the restroom.
"I noticed he was in there for a while, but I didn't make a big deal about it," she said to KSAT-TV.
Jimenez said Albert was wearing a backpack, brown pants, surgical mask and sunglasses.
She said Albert exited the restroom and approached her.
"I was kind of weirded out," Jimenez said. "(Albert) was looking at me and he was saying something about, 'Do you know where the nearest church is at?'"
Thinking he was trying to find a service to attend, Jimenez pointed out the Door Christian Fellowship Church, which is located directly next to the restaurant.
"He was like, 'I've been to that church many years ago,'" Jimenez said.
Jimenez said she asked her mother, who owns the restaurant, if she knew where other Baptist churches were and her mother provided Albert with directions. Jimenez said Albert repeatedly asked if she could take him to the church, even after she explained that she couldn't because she was working.
That's when Jimenez says she noticed Albert was armed.
"He's gripping it, like, he has his finger on the trigger," Jimenez recalled.
She said she remained calm and kept her eyes on Albert as he exited the restaurant to see where he was headed. She then called out to another employee to very discreetly lock the door so as to not alert Albert. Then Jimenez's mother called police.
There weren't customers in the restaurant at that time, Jimenez said.
Jimenez and her relatives took cover and waited for police to arrive.
While Jimenez didn't immediately think of the possibility that Albert could have been up to something criminal, she said others have called her a hero for having the instinct to have her mom report the suspicious behavior.
"Now that I think about it, he could've taken a trip to any church and -- a lot of people leave in body bags," Jimenez said. "That kind of hurts me, like, what if? You know what I mean? What if that really happened?"
Police spokeswoman Tanya Brown said an off-duty officer caught up to Albert in the 2200 block of West Kingsbury Street. According to authorities, Albert said he was on his way to an unknown church to fulfill a prophecy.
"We're extremely grateful (for the person who called 911), and I know the citizens of Seguin are (grateful)," Brown said. "(Albert) could have carried out a shooting, or he was capable of doing that, because he had a loaded handgun."
Brown said it's unclear what exactly Albert's intentions were, namely whether he intended to carry out a shooting. She said that the Texas Rangers, FBI and Bureau of Alcohol, Tobacco, Firearms and Explosives have been called in for assistance in interviewing Albert.
