SOUTHWEST PHILADELPHIA (WPVI) -- Police say a store clerk in Southwest Philadelphia is being sought for shooting a customer after an argument.It happened on around 12:20 p.m. on June 3rd at the Nilo Food Market in the 4500 block of Parrish Street.A customer walked into corner store and asked for change for a $20.That's when things took a turn for the worse. The store clerk claims the $20 bill is a fake.Surveillance video shows the pair as they begin to argue.The store employee is seen on the video grabbing an aluminum baseball and shoving it through the glass opening at the customer."It should've just been dealt with as adults. The victim is 38, the employee in this case is between 45 and 50. These are not kids, these are adults," said Lt. John Walker, Philadelphia Police.But the argument escalates even further.Upset that the money may be counterfeit, police say the store clerk pulls out a .38 caliber handgun and fires at the customer in close range.The customer was struck once in the back and once in the hand. He was taken to Penn Presbyterian Hospital where he's still recovering."This is a classic incident where you have access to a weapon, people get hyped and then you use something that really shouldn't have been used. It was just an argument," said Lt. Walker.Another store employee steps in and tries to stop the clerk from shooting but it's too late.With the customer wounded, the store clerk fled the store and hasn't been seen since.He's believed to be in his 50s and possibly goes by the name Pablo Torres or Pablo Rodriguez."We have not had any cooperation from the owners or the people who work at the business. We know people may know this person, may know his real name and we're just looking to get him off the streets," said Lt. Walker.Anyone with information is urged to contact Philadelphia Police at 215.686.TIPS (8477) or text a tip to PPD TIP (773847).
