Her family still grieves and is frustrated, but even all these years later, they remain hopeful that someone may come forward with helpful information to find the suspect responsible.
Amy's son, Michael Francis, was 13 years old when he was walking with Amy at a crosswalk at the intersection of Jupiter Road and McCree Road on the afternoon of Jan. 26, 2005.
"Honestly, it gives me nightmares, just seeing what I saw," he said.
What Michael saw was a car turning onto Jupiter Road, clipping his leg. He says his mother turned to help as the driver backed up, raced forward, ran over her and just kept going.
Amy was taken off of life support two days later, leaving behind her children and her loving husband of 20 years.
"It kind of made me angry that no one spoke up," said Michael. "I know maybe it may be a friend your family or whatever, but do the right thing. I lost my mother and nothing replaces that."
Michael has a few pictures and fond memories of his mother.
"She was a ball of joy," he said. "She loved everything! She used to always tell me, ‘Your day can never be bad. If you want it to start over, just say my day starts over now.'"
FOX 4 asked Dallas police for an update on the case, but we have not yet heard back.
Michael, now 23, is expecting a child of his own in about a week who will be named after Amy.
