While Mumby survived, Waterman later died from his injuries. The jury reached the verdict in just over an hour, rejecting the defense's claim that the crash was accidental.
Back now with our big story at 5.30, the girlfriend is guilty.
A jury took just over
an hour to decide Leah Mumby purposely crashed
this car with her boyfriend inside after a heated
argument over a text message.
That boyfriend survived the horrific crash but was left in a
coma before waking and later dying from his injuries.
Mumby was convicted of vehicular
homicide and reckless driving.
Marie Ettinger has more on today's verdict.
Leah Mumby's family broke down as the jury read out the verdict.
But prosecutors pointed out Mumby is still here.
Her boyfriend, Daniel Waterman, is not.
We, the jury, find the defendant, Leah Mumby, as follows.
Count one.
Guilty of the charge of reckless driving
with serious bodily injury as charged in the information.
A jury says Mumby was arguing with Waterman,
accusing him of cheating on her while she was pregnant with his child.
She was driving and accelerated to over 90 miles an hour,
driving straight into a tree.
We've got a woman who's enraged and driving in a way
that is extremely aggressive because she's extremely angry.
She's not thinking about her unborn child at that moment.
She's just extremely angry
and reacting that way in the heat of the moment.
Mumby's attorneys argued she lost control of the vehicle.
She didn't crash it on purpose.
They said data from her vehicle showed she did slow down
and made other efforts to stop the crash.
There's absolutely zero evidence or reason to believe
that she was in a place where she was going
to put all of their lives, including hers
and that of her unborn child, at risk of serious bodily harm or death.
Her efforts to avoid the crash, as soon as that input gets made,
illustrate that she never intended
for that to happen in the first place.
But the prosecutor says any last-minute attempt to stop things
doesn't change that she started toward the crash in the first place.
The jury agreed, and they came back
with a verdict after just an hour and a half.
Next, a judge will decide what sentence Mumby will face.
The vehicular homicide conviction is a second-degree felony,
which could mean 15 years behind bars.
