PHILADELPHIA (WPVI) -- A store clerk is in "extremely critical condition" after a man shot him in the head at point-blank range following an argument, according to Philadelphia police.
Investigators said the man shot the victim, 55, just before 10 p.m. Wednesday at the Vargas Mini Market, which is located at East Cambria and Kip streets in the city's West Kensington section.
The shooter is described as a man in his late 20's, wearing a hoodie, jeans with bleach spots and a blue surgical mask.
Witnesses told police the shooting stemmed from an earlier argument that occurred 15 minutes prior. Police said the shooter came back to kill.
Clear surveillance video shows the shooter walk into the store, fire a shot at the victim, then run behind the counter and fire a second shot at point-blank range, according to police.
Investigators said the victim was unresponsive and rushed to Temple University Hospital for emergency surgery.
The victim lives above the store, but police said he doesn't own the business.
East Detectives are working to track down the suspect.
