PHILADELPHIA (CBS) — Four teenagers are hospitalized with gunshot wounds after gunfire erupted Friday night in Philadelphia’s Frankford section. It happened shortly after 10 p.m. Friday on the 1300 block of Sanger Street.

It’s another example of gun violence beginning to absorb younger and younger groups of people.

The quadruple shooting affected two 17-year-old girls, an 18-year-old man and a 19-year-old man.

It happened on the 1300 block of Sanger Street in North Philadelphia around 10 p.m.on Friday. All four victims were transported to area hospitals, where they were said to be in stable condition overnight.

But it continues to be a disturbing trend in Philadelphia. Shooting victims are up nearly 46%, according to police statistics with a staggering amount of victims being minors.

According to Philly police, 22 people under the age of 18 have been killed this year due to gun violence.

Renee McDonald is a member of Mothers in Charge, an anti-gun advocacy group in the city. McDonald says not enough emphasis is being placed on helping young people specifically, men, deal with their emotions.

“We don’t have enough of that. We don’t have enough people who are actually dealing with the hurt, the pain, the anguish. What do you do with it?” McDonald said. “When it comes to our young males, they feel they don’t know how to ask for help, they don’t know how to act out and sometimes they act out in anger and that’s a lot of what we’re seeing here.”

No arrests have been made so far and no weapons have been recovered as the investigation is ongoing.
