Crime Alert, I'm Nancy Grace, breaking crime news now.

Andrea Vesquez, 19, and her boyfriend parked their car

at a California park after dinner.

Not long after, an armed man approaches the car

and starts shooting at the couple.

The boyfriend runs for help when he comes back.

The passenger seat is bloody and Andrea is gone.

Cops track Andrea's phone and find her body in a field.

Cops ID the shooter is Gabriel Esparza.

Nancy, the attack appears to be entirely random.

Vesquez was missing for nearly 24 hours

before officers discovered her body alongside her cell phone,

which they had been attempting to track her with.

Esparza, who has no criminal record,

apparently gave a detailed confession of the attack

and he was arrested the afternoon

before Vesquez was discovered.

Esparza 20 plays not guilty to murder, kidnap,

and attempted rape.

Florida cops pull over Jeffrey Kaufman for speeding

and they're hit with a strong smell of pot

as they approach the car.
