MARRERO, La. (WGNO) — When Wizard World Comic Con was in New Orleans, we brought you the story of a teen battling cancer, who’s wish came true, to meet the cast of ‘The Walking Dead.’ Months later, he’s still facing an uphill battle. Now friends and strangers are coming together to help save his life.

On a cold, rainy day in the Lowe’s parking lot in Marrero, one person after another enter two bloodmobiles, hoping to save a life.

“He has cancer and he’s a good person,” says friend Viola Punch.

Arthur Wear has been battling soft-tissue sarcoma since his 17th birthday last fall. In January, he had some relief from the darkness, as his wish was granted to meet the cast of ‘The Walking Dead.’ during Comic Con. Now, with one endless procedure after another, Arthur is in dire need of blood.

“When you see all these kids die from this, of course, it puts more fear into you because I’m sure their parents prayed just as I did, and I understand everybody has their own destiny,” says Arthur’s mother Sherry Tolar.

Ochsner stepped in to help a mother desperate to save her son. A revolving door of loved ones came in, donating, and sharing their stories.

“He didn’t even get to live his life yet, you know,” says friend Ashton Snyder.

“No matter if you’re 17, 20, 50, I don’t think anybody should have to go through that,” says friend Madison Plaisance.

“All I can do is hold his hand and help him out any way I can. I’m kind of like his nurse when I’m in the hospital with him,” says friend Rachel Romano.

Selfless strangers, who’ve never met Arthur, are rolling up their sleeves to help.

“I would tear up a little bit if I see him. I’d be like, “Man, I donated blood for you,”” says Brendan Pillow.

What Arthur can’t use will help other transplant, trauma and cancer patients at Ochsner.

“Without blood supplies, the medical field would pretty much shut down. We need blood for almost everything we do,” says Mickie Wilson-Martin, a donor recruitment specialist at Ochsner.

In a tight space, people who’ve never met came together to save a life. You can call them ‘Arthur’s Army.’

“It feels wonderful. I can’t even begin to express the gratitude I have. People I have never met or seen are coming out to show support for this kid,” says Tolar.
