Now, these nameless and still faceless killers have another reason to be scared: The reward for their arrest and conviction has risen to $30,000.
"We're going to find out who did this," Clark said.
The video shows that the two men who killed Long while she walked with her mother on Front Street near Poplar at 10:37 p.m. were riding in a dark-colored newer-model four-door Chevy Impala with tags on both the front and rear. It also shows a third man driving the car.
The three appear to have been scouting the area for victims, according to Clark.
"They're trolling," he said. "It's a possibility that they were actually watching them way before they confronted them."
In the video, the encounter lasts mere seconds. The taller of the two men is able to grab Long's mother's purse easily and run away, but when the shorter man tries to grab Long's purse, her body is turned with the force of his pull and he shoots her.
He ran away and left the purse, a dying Long and her traumatized mother behind.
"Her daughter died in her arms," Clark said.
Police are still processing additional surveillance video that might provide a better picture of the car or the suspects.
Clark said a bad lead from Lamar Beatty, 44, led them down the wrong road early in the investigation and as a result, detectives are "a little behind the eight ball." Beatty was charged with false reports to police after he called 9-1-1 and told detectives that he knew the men responsible for the killing.
It turned out that Beatty had lied because he was trying to pin the killing on two drug dealers to whom he owed a debt, Clark said.
Tipsters are urged to call 215-686-8477.
