Steven Paula Guilty in Road Rage Attack His Daughter Snapchatted

"Thank God for stupid teenage girls and social media."

So said Mason Deal after a jury convicted Steven Paula of punching him out in a road rage incident that we featured in a Schmuck of the Week post in 2014 — and for a very good reason.

Turns out the best evidence against Paula was provided by a screen capture from a Snapchat video of the assault taken and shared by his daughter.

As we've reported, the tale originally told by Fox31 began at around 4:55 p.m. on November 8.

Mason Deal, eighteen, was driving near Jordan Road and Bradbury Parkway, at a point where a pair of lanes merge into one.

According to Deal, a minivan tried to pass him rather than yielding, and the two vehicles made contact.

A moment later, Deal stopped and watched the minivan's driver dismount.

But instead of offering to exchange insurance information, the guy punched Deal in the face, giving him a concussion.

Moments later, Mr. Minivan split, and since Deal had been incapacitated by the blow, he probably would have gotten away clean.

Why didn't he?

Turns out Paula's daughter had taken some video of the incident and sent it to a friend on Snapchat.

Items on Snapchat are supposed to vanish after viewing, but canny users know how to grab screen shots.

That's what happened in this case — after which the daughter's friend sent this image....

...to someone who knew Deal.

You can guess what happened next.

After receiving a copy of the image from Deal's family, investigators with the Parker Police Department traced it to Paula, who has previous convictions for burglary and forgery.

He was subsequently arrested on suspicion of misdemeanor assault, leaving the scene of an accident and harassment.

During the trial, Paula's lawyer reportedly claimed that Deal cursed at him — and he insisted that he'd leveled the teen to protect his kids, including his Snapchatting daughter.

But the jury members weren't convinced. Although they acquitted Paula on the harassment beef, they found him guilty of the other two counts against him. He's expected to be back in court on May 25, when he could be sentenced to as much as two years behind bars.

No word about whether Paula's daughter still has phone privileges.
