As she fell, the bike's handlebar brake hit her neck, severing an artery, WDRB reported, citing LaRue County Sheriff Russell McCoy. The sheriff said the girl's mother, Tiffany Fischer, found her and carried her around 200 feet back to their home, but she never recovered.
Fischer wrote on Facebook Saturday that her daughter "is smiling right now" seeing the news coverage of herself, as "she always wanted to be famous."
"I think she would have been a comedienne. She loved Adam Sandler. Ellen [DeGeneres] made her laugh hysterically, [as did] Robin Williams. Now she's up there with our family listening to some of Robin Williams standup acts," Fischer said.
Fischer said she's "a mother who lost her entire heart. I lost my entire world on Tuesday. I loved that little girl with every ounce of my being. I lived because of her. She gave me purpose."
"She would be smiling and laughing right now. I love you so much, baby. So, so much," the grieving mother added. "But you will live on. You are still here. You will not be forgotten."
A GoFundMe page set up for the Sipes family with a goal of $2,000 had raised nearly $13,000 as of Monday. The organizer, family friend Lisa Deweese, told the Louisville Courier-Journal losing a child is unimaginable.
"I just wanted to help in any way I could."
Charlie was a third grader at Abraham Lincoln Elementary School in Hodgenville, according to her obituary, which said the child is survived by her parents, grandparents, a great-grandmother and four siblings. The school's principal described Charlie as "a charming, caring student who was loved by her teachers and her peers."
