KILLER APPS

Is social media making America's murder surge worse?

- ALEC MACGILLIS

One fall evening in 2020, Jarell Jackson and Shahjahan McCaskill were chatting in Jackson's Hyundai Sonata, still on a postvacation high, when 24 bullets ripped through the car. The two men, both 26, had been close friends since preschool. They'd just returned to West Philadelphia after a few days hang gliding, zip-lining, and hiking in Puerto Rico. Jackson was parked outside his mom's house when a black SUV pulled up and the people inside started shooting. Both he and McCaskill were pronounced dead at the hospital.

In the aftermath, McCaskill's mother, Najila Zainab Ali McCaskill, couldn't fathom why anyone would want to kill her son and his friend. Both had beaten the odds for young Black men in their neighborhood and graduated from college. Jackson had been a mental-health technician in an adolescent psych ward while her son had run a small cleaning business and tended bar. She wondered if they'd been targeted by a disgruntled former employee of the cleaning business. But then the police explained: Her son and his friend had been killed because of a clash on social media among some teenagers they'd never even met.

For months, a battle had been raging on Instagram between crews based on either side of Market Street. Theirs was a long-running rivalry, but a barrage of online taunts and threats had raised tensions in the neighborhood. Police had assigned an officer to monitor the social-media activity of various crews in the city, and the department suspected that the Northsiders in the SUV had mistaken one of the two friends for a rival Southsider and opened fire. An hour after the shooting, a Northsider posted a photo on Instagram with a caption that appeared to mock the victims and encourage the rival crew to collect their bodies: "AHH HAAAA Pussy Pick Em Up!!"
