NORTH PHILADELPHIA (WPVI) -- Police have identified the man charged with murdering his co-worker as she waited for a bus in North Philadelphia.36-year-old Randolph Sanders has been arrested and charged with the murder of 56-year-old Kim Jones.Police say Sanders was brought in to speak with homicide detectives on Saturday, during which time he allegedly confessed to the murder.According to police, Sanders killed Jones because she was going to report him for the alleged theft of funds from the nonprofit where they worked.Captain James Clark called the killing a "premeditated assassination style murder."Deputy Commissioner Richard Ross said at a press conference Monday, "This is the type of investigation that leaves you angry and confounded."The shooting happened around 9:30 a.m. Tuesday, January 13th at 12th and Jefferson Streets in North Philadelphia.Police say Jones was waiting for the Route 23 SEPTA bus. She had headphones in her ears and was listening to gospel music at the time.That's when, according to investigators, Sanders, dressed in a disguise, quietly walked up from behind and shot her in the back of the head."We're all just stunned, just stunned, just stunned," he said in a January 14th interview."A psychopath can do something crazy like that - kill a human being and not think anything of it," said Jean-Paul, Jorden, victim's son.The victim and Sanders ran a program for Turning Points for Children on South 15th Street, which has a contract with the city's Department of Human Services."That was the main goal of her life - just to give and not take. And the fact that this guy's main goal was to take," said Jorden.Captain Clark says that Jones hired Sanders two years ago as an assistant director for the non profit organization.However, Jones allegedly accused Sanders of mismanaging funds and possibly stealing thousands of dollars from the nonprofit.Police say the preliminary investigation into the theft estimates the total amount stolen at $40,000.On the morning of her murder, police say Jones was on her way to DHS to report Sanders.On Sunday, detectives were back on the scene with a metal detector looking for evidence.However, Clark says surveillance video of the shooter led them to a vehicle, which led them to Sanders.Clark says surveillance cameras captured the suspect through Temple University's campus, onto the subway system and exiting the subway at Broad and Hunting Park. The cameras then captured the suspect walking to a vehicle, a 2007 GMC Yukon, parked on the 4200 block of Carlisle Street.Detectives' big break in the case was when they realized Sanders drove the same type of vehicle.Police took Sanders in to custody at his Northeast Philadelphia home on Ryerson Road, where they searched the residence and also found three guns.Jones' son continues to ask why?"To find out that that's the reason that I will never see my mom again and I'll never talk to my mom again and my inspiration is gone for life - i's heartbreaking," said Jorden.As for the alleged theft of funds from the nonprofit, those accusations are still under investigation.Michael Vogel, CEO Turning Points for Children released the following statement amid the news:
