A Ring camera captured the moment an 18-year-old man was shot dead by his assailant in Philly, moments after his friend was killed as well.

Joesph “Zu” Humphrey, 20, allegedly slapped someones mom, and girls at the scene wanted to fight him. Humphrey, who didn’t want to fight them back, called some female friends to come and fight the girls.

At that point, one of the girls who’s mom got slapped called some male friends for backup, who came and shot Humphrey dead moments before gunning down 18-year-old Kalil “Bump” Stamford.
