PHILADELPHIA (WPVI) -- Philadelphia police are searching for three gunmen after a teenager was killed execution-style on Tuesday afternoon.
"Unfortunately we are here once again to report another senseless murder in the streets of Philadelphia," said Homicide Unit Commanding Officer Staff Inspector Ernest Ransom as he addressed the media at Philadelphia Police Headquarters.
The fatal attack happened at around 4 p.m. in the 1200 block of Van Kirk Street in the city's Oxford Circle section.
It's where 16-year-old Jamil Wyatt was walking. Police saw the crime unfold on surveillance video.
"The victim was walking through the rear driveway of the store by himself when three individuals dressed in all black and had masks on exited a white 2013 Nissan Sentra," said Ransom.
They had their sights set on Wyatt who ran from the individuals.
"They began to chase Mr. Wyatt through the driveway, firing their weapons," said Ransom.
After Wyatt collapsed in the driveway, video reportedly shows at least two gunmen standing over him while shooting at him just a few feet away.
"He then falls to the ground and the shooters began to shoot again as he is on the ground," said Ransom.
Police recovered about 60 fire cartridge casings from the scene, showing just how many shots the shooters fired at Wyatt. Officers found the 16-year-old victim suffering from multiple gunshot wounds while lying on the ground behind a home on the block.
He was rushed to an area hospital where he later died.
"One would believe he was targeted but we'd have to look into that as part of our investigation," said Ransom.
The suspects were last seen fleeing in a white Nissan Sentra with light-tinted windows.
Philadelphia police are now asking the public for help.
"We believe an arrest can be made for the murder of Jamil Wyatt," said Ransom, adding a petition for tips from the public.
"If you know something you've got to say something. You've got to tell us what's going on," he said. "It would help us in our investigation immensely."
