Two North Carolina florists were being called heroes Thursday after their 911 call led to the arrest of suspected mass killer Dylann Roof in Shelby, North Carolina, the Shelby Star reported.

Debbie Dills was driving to her job at Frady’s Florist early Thursday on Highway 74 when she first spotted Roof, the suspect in the killing of nine people inside an historic black church in Charleston, S.C.Wednesday night.

“I saw the news coverage last night and the picture of the car. I knew it was a black car, and it had a tag on the front. I saw the picture of him with the bowl cut,” Dills told the Shelby Star. “I said, I’ve seen that car for some reason. I look over, and it’s got a South Carolina tag on it. I thought, ‘Nah that’s not his car.’ Then I got closer and saw that haircut.”

Dills called her boss Todd Frady to ask for his advice. “I had the worst feeling. Is that him or not him?”

Frady told the paper he immediately called officer Shane Davis of the Kings Mountain Police Department, who told Shelby police that Roof’s Hyundai Elantra was spotted traveling west on Highway 74.

According to the paper, Dills continued to follow Roof’s car until police got there.

Twenty minutes after Dills’ phone call to her boss, Shelby police pulled Roof over and he was apprehended.

“I had been praying for those people on my way to work,” Dills told the paper. “I was in the right place at the right time that the Lord puts you.”
