Crime scene investigators spent Sunday morning searching for new evidence at the scene of an execution-style murder of a child advocate at a North Philadelphia bus stop last month.
Using a shovel and metal detector, investigators looked for clues that could point them to Kim Jones' murderer.
The 56-year-old newlywed and mother of two was shot in the back of the head as she waited for the Route 23 SEPTA bus at 12th and Jefferson Streets on the morning of January 13.
Investigators returned to that corner at 9:15 a.m. Sunday and dug holes in a patch of grass next to a small memorial for Jones. They also uncovered a manhole and swept the area nearby, including trolley tracks buried in the street, for evidence.

Homicide detectives said the shooter, dressed in all black and wearing headphones, stalked the victim. They waited over an hour outside Jones' home before following her to the corner and pulling the trigger.
Surveillance video captured the shooter calmly place the weapon in a black duffle bag following the shooting and walk away.
"This was a very well planned execution," Philadelphia Police Homicide Capt. James Clark said last month.
Police believe the shooter knew Jones. Sources tell NBC10 they are not ruling out the possibility that a woman may have been holding the gun.
After sweeping the scene again, detectives traveled some 20 blocks south to Philadelphia Police Headquarters where sources say they are questioning people who knew Jones.
Sources said investigators hope to make an arrest soon.
