Dylann Roof Was Left Out of Sister's Weekend Wedding

As details of the massacre continue to emerge, INSIDE EDITION reveals that Dylann Roof was left out of his sister's upcoming wedding, which has

The sister of Dylann Roof, the 21-year-old gunman who murdered nine people in a Bible study group, was supposed to get married this weekend.

She was scheduled to marry an Army Reserve recruiter, but the wedding's been called off. It was supposed to be on Sunday - Father's Day - at a popular wedding venue in North Carolina.

Amber, 27, was one of the people who alerted authorities after recognizing Roof in surveillance video. He was caught just three miles from her home in North Carolina.

In Amber and Michael's wedding blog, Amber looks overjoyed at her bridal shower. The groom and a group of buddies took the ice-bucket challenge and posted a video.

Perhaps significantly, there was no role for Roof in the wedding party. Rev. Tony Metze, the family pastor, appeared on CNN: "We continue to hold all these families in our prayers, and that the whole world, our nation, Charleston, our community, understand that we love them," he said.

And we're learning more about Roof's 15 hours on the lam. After fleeing Charleston, he drove 185 miles to a Shell station near Charlotte, North Carolina at 5:50 a.m. He bought a bag of Doritos and a bottle of water and used an ATM machine to get cash.

After the stop, he drove onto U.S. 74 and that's when he was spotted by Debbie Dills, who was on her way to work at a florist shop. She recognized his distinctive bowl-cut hair style.

“I couldn't believe that it was him, but it was him," she said.

She called her boss, Todd Frady, who alerted police. She tailed Roof for 25 miles until he was cornered by cops at 10:44 a.m.

“When I realized who it was, I was just thinking of the pictures I had seen of the people there in Charleston, who were holding hands in a prayer circle and who were calling out to God for an answer to their prayers," she said.

Today she is being hailed as a hero - but she says her thoughts are with the grieving city of Charleston.

“My heart is with those people in Charleston, those families that have lost their loved ones. And my heart is there with them," she said.

Roof's own uncle has no sympathy for him. He hopes Roof is going to "ride the lightning," meaning get the death penalty. He said, "I'd pull the switch myself if they'd let me." [Source: Los Angeles Times]
