An Oklahoma mother who welcomed her miracle daughter just two years ago was tragically mowed down in a freak sledding accident — and her two friends who were behind the wheel were charged with her murder. 3 Makayla Mitchell, 31, was run over during a sledding accident in Oklahoma on Sunday. Kirk faces an additional charge for child endangerment, though it’s unclear if Mitchell’s 2-year-old daughter was involved in the accident. 3 Angel Walzier, 22, was driving the car that Mitchell’s sled was tied to. In Texas, 16-year-old Elizabeth Angle died in a similar sledding accident on Sunday.
