There are still plenty of unanswered questions about the chain of events Friday afternoon on the outskirts of Marionville. The biggest question is why it happened.

Friends and family of Joseph Michael Rich, also known as "Big Mike," talked about him on Saturday. Big Mike was that Good Samaritan who slowed down at the sight of someone who needed help. It cost him his life, and his family and friends are remembering what they loved most about Mike, whose life was taken for seemingly no reason.

Business has been put on hold at Atlantis Tatoo, Big Mike's second home.

"He taught me how to tatoo," said Atlantis Tatoo owner Tom Cooney, who knew Mike for 10 years.

Cooney and other friends and family are trying to grasp what's happened.

"There's a hole about this big around in all of our lives," Cooney said.

Rich was on his way to work in a small, white bus, a mobile tattoo parlor. He slowed to help the victims of a car accident, when Jesse Miller fatally killed him with a shotgun blast.

"Did the guy have medical problems? Did he have a psychological problem? Was he on drugs? I have no idea what was wrong. Why? And that makes it a little harder to understand," said Cooney.

Though they can't understand it, Big Mike's loved ones are holding onto their memories of him.

"He tried to always act like he could take on the world, and convinced us he was invincible, and he always was," said Rich's daughter, Anita Grant.

They say he loved his career, on the road and at Atlantis Tatoo, creating art in black and gray. And he wore his own artwork too.

"He had some pumpkins on his arm, and nobody knows what they meant but they meant something to him, and they were special to him," Cooney said.

His daughter has learned the secret.

"Yeah, I always asked him, too, and he finally mentioned it one day. What did I think it was? And I said, 'Well, there's three of them, and you just happen to have three kids,' and he just smiled at me, and told me, 'Yeah.' That way, he always had us with him, no matter where he was," Grant said.

And though his loved ones wish he were still with them, instead of senselessly losing his life, ironically, across from a pumpkin patch, they'll always treasure his memory. And his daughter wants to remember him for what he loved: tattooing.

"I don't like the thought of someone else giving it to me besides him but I think I'm going to get one, at least, in memory of him," Grant said.

Though they don't know why this tragedy happened, Rich's family say they realize they're not they only ones grieving right now, and pray for the family of the gunman too.

A reporter contacted Miller's family by phone but they did not want to comment at this time. The motive is still unknown. Marionville Police Officer Andy Clark was airlifted to a hospital in Springfield for his injuries. He has been released; no word on when he'll return to work.
