He made it a few steps before the bullet hit his spine.

The 30-year-old had been running from would-be robbers in Kingsessing, young men who initially demanded money but settled for target practice as he bolted in fear. He lost feeling in his legs the instant he was shot, at 54th Street and Warrington Avenue. The attackers scattered without even taking his wallet.

It was just after midnight on a Thursday last month. Lt. John Walker arrived at the crime scene, ducking under yellow tape and walking toward the bloodied pavement.

In a city with more than 1,000 shootings a year, this had long been the typical start to an investigation. But things are changing. Before Walker even stepped out of his car, a team of officers in a room five miles away already was working the case — remotely scanning for surveillance cameras in the neighborhood and diving into databases to find potential leads about the victim and who might have had reason to target him.

In minutes, that intelligence bureau's handiwork — an email report — landed in Walker's inbox, easily accessible from his phone. It's all part of a new effort that the department says reflects its continued attempt to drill down on blocks plagued by gun violence.

Across the city, shootings are down about 6 percent compared with last year's pace, and overall violent crime continues to decrease. But in some neighborhoods, like Kingsessing, it seems the gun violence never ends.

Since the beginning of 2015, according to police statistics, 86 people have been shot within a half-mile radius of the intersection at 54th and Warrington. That's five times as many as in all of neighboring University City.
