There will be clues which will soon lead to the suspects ID. Like possible spent casings, a bullet. And they'll pull every street view video within 2 miles of the location. It was about 130 a.m. Not too much traffic then. Plus they're not saying if the LEO provided any description on the suspects, vehicles etc when he called it in. And what did the neighbors see after the shot?
They have to be tight lipped here. They don't want to spook these SOBs into the tall grass. I'm confident they will get these guys.
