We spoke to a customer who left that gas station just minutes before the murder. He says he saw the suspect there, but he was dressed differently and the man says he had no idea what he was up to.
"I saw him real good," said the customer, who asked us not to identify him. "I got a good look at him."
The customer says he was at the Chevron station and saw the suspect walking around. But he says at the time, he was wearing different clothes.
"He had a black kind of do-rag, short sleeve shirt, nice looking hair, clean-cut looking, handsome young man," said the customer.
He says he became suspicious after the man in the surveillance video began looking into his vehicle, and then disappeared.
"I looked around for him and didn't see him, so I assumed he was probably in the back of the store," said the customer.
The customer left the store and minutes later, police say the man who showed up again was armed with a gun and grabbed a woman's purse. Irick intervened in the robbery and the suspect shot him in the chest, killing him.
The customer says he won't ever forget his face. He now hopes the suspect will pay for what he has done.
"It doesn't surprise me one bit," said the customer. "He just looked like trouble."
We also spoke with Irick's mother today. She was too distraught to talk on camera, but told us her son was selfless, always helping others. In fact, she says she had a conversation with him recently about not stepping in when there's danger. She says she's heartbroken and she'll miss him dearly.
