PHILADELPHIA (CBS) — A CVS parking lot in East Germantown turned into the scene of a deadly shooting Saturday. It all started as an attempted carjacking and turned deadly after shouts for help.

The attempted carjacking happened in broad daylight in the CVS parking lot on the 6300 block of Stenton Avenue in Philadelphia’s East Germantown neighborhood just after 12:30 p.m.

Philadelphia police say they believe the suspect is the man who was shot and killed.

Police say a 59-year-old man sitting in his car was approached by a 20-year-old man who tried to rob him and take his vehicle. The two struggled in the CVS parking lot, according to police.

The victim eventually started to yell for help, police say.

According to police, a security company supervisor allegedly came to the rescue, discharging his weapon and striking the suspect three times.

The alleged offender was rushed to Einstein Medical Center, where authorities say he was pronounced dead a short time later.

Authorities say officers did manage to recover a weapon, while the victim and the good Samaritan are cooperating with police.

“I just think it’s a tough time. We have a pandemic going on. Nobody’s making any money. It’s a lot of unfortunate events happening. We’ve got a plethora of firearms on the streets. Our schools are bad,” Michael Cogbil, of Germantown and lives in the area, said. “I don’t think it being in this parking lot or being up the street or being in North Philly or in West Philly would make any difference. This is a trying time for everybody.”

Philly police say the homicide unit remains actively investigating the shooting.

So far, no charges have been filed.
