Josh Pinkard of Oswego, Ill.

Plant manager Josh Pinkard worked at Mueller, the company that owns the brand Henry Pratt, for 13 years, the company wrote in a statement. He had previously worked at a plant in Alabama, but had been relocated to the Aurora facility last spring.

His wife, Terra Pinkard, recounted what had happened Friday in an emotional Facebook post.

Soon after Josh Pinkard was shot, he texted his wife to tell her what happened and that he loved her, the post said.

When he didn’t respond to her calls, Terra Pinkard tried calling the plant, and a worker told her that she’d had to barricade a room and that the plant was filled with police.

After picking up their three children, Terra Pinkard tried looking for Josh at one hospital, and then another. Eventually, she got in touch with the police, who told her to come to the staging area for victims’ families.

“With my pastor’s help, since family was still on planes to get to us, I told my children their dad did not make it and is in heaven with Jesus. I’ve never had to do something that hard,” Pinkard wrote.

She continued, “I literally can’t talk out loud about this lovely man without breaking down in sobs. I’m crying now as I write this. I want to shout from the rooftops about how amazing Josh was! He was brilliant! The smartest person I’ve ever met! My best friend!”
