This year, up until Saturday, there had been 1,939 shooting incidents in the city a 7 percent increase compared to the previous year.
Between May 23 and Saturday, there were 349 shootings, according to weekly data from the Philadelphia Police Department, an increase of just below 5 percent from the previous month.

The violent attack that took Mr. Laylos life is heartbreaking and our thoughts are with his family during their time of grief, the spokesperson told the outlet. We hope the police are able to quickly arrest those responsible.
