Leigha Mumby Faces Vehicular Homicide Trial in 100 mph Florida SUV Crash

Prosecutors told jurors Leigha Mumby deliberately steered an SUV off I-95 in February 2025 after arguing with boyfriend Daniel Waterman over another woman’s texts, opening her Florida vehicular homicide trial.
Vehicle data showed speeds above 100 mph and 94 mph in the final seconds before an abrupt 45-degree left turn into the woods, which prosecutors called a reckless maneuver.
Defense lawyer Reid Hart said the case turns on a single steering input and argued something inside the SUV triggered the swerve beyond Mumby’s anticipation or control.
Waterman, 22, suffered a broken neck, paralysis and months of medical complications before dying on Oct. 8, 2025; prosecutors then upgraded Mumby’s charges from serious-injury counts to vehicular homicide.
Jurors will not hear Waterman’s own account accusing Mumby of swerving intentionally, after the judge ruled his statements to detectives inadmissible under evidence rules.
