Leigha Mumby
In short
Leigha Mumby is a Florida woman convicted of vehicular homicide and reckless driving following a fatal high-speed car crash in 2025. A Flagler County jury delivered the verdict on 14 October 2026 after rejecting her defence that an outside force caused her to lose control.
In plain words
Mumby was driving at nearly 100 mph when she crashed, killing her boyfriend, Daniel Waterman. She claimed the crash was an accident caused by something external, but the jury did not believe her. She was found guilty of causing his death through reckless driving.
A simple example
After an argument and learning she was pregnant, Mumby drove her vehicle at speeds exceeding 94 mph, resulting in a fatal collision.
Why it matters
The case highlights the legal consequences of extreme speeding and reckless driving following personal disputes. It also drew media attention due to comparisons with other high-profile vehicular homicide cases.
Easy to mix up
Do not confuse her with Mackenzie Shirilla, a different woman involved in a similar high-profile high-speed crash case.
