Las Vegas police still don't know what set off the incident, what prompted the driver of a gray Honda Accord to hit an man and leave him writhing in pain on the pavement of Las Vegas gas station.
In the two weeks since the incident, the motorists has eluded them.
But they do have one thing: surveillance camera footage. And like other enforcement around the country, they think by releasing the video, by posting it online, they'll get the help they need.
The start of the video seems mundane.
Cars line up to get gas, people coming and going.
Then, a gray Honda Accord pulls into the parking lot of an AMPM gas station.
The Accord cuts off a man's car. The man, wearing a red cap and sweatshirt, drives around it to avoid an accident.
Later, as the man crosses the parking lot, the Accord drives up to him, nearly clipping him. Then the car moves forward, bumping the man and running him over.
