Forgiveness and reconciliation at New Life Church, Colorado

Great news at CNN, Killer's parents hug, cry with parents of 2 slain teens

The pastor said he invited the Murrays to visit the New Life campus after praying over the holidays. The family immediately accepted his invitation and was given a guided "step-by-step" tour of where the rampage took place and shown where their son died.

"It was extremely emotional. They wanted to hear the details. I kept telling them I would stop with details, but they wanted to hear them," he told CNN in a phone interview this week.

At one point, the parents also met with security guard Jeanne Assam, who shot their son in the leg before he turned his gun on himself. The parents thanked Assam for her swift action and for helping save more lives, said Casey Nikoloric, a Murray family spokeswoman and long-time friend.

"They told Assam that they were so deeply sorry she had to do what she did," said Nikoloric. "There were tears, lots of embraces, prayers."

The visit, she said, was "very, very, very important" in the healing process for the Murrays as they deal with the loss of their son and the terror he inflicted.

Forgiveness is one of the foundations of Christianity. It's so awesome to see it being practiced in such difficult situations. I had several posts on this tragedy last month. 1, 2, 3, 4, 5, 6, 7, 8, 9, 10.
