PHILADELPHIA (AP) — A gunman wearing a bulletproof vest opened fire in Philadelphia Monday night, killing four people and wounding two others, police said.
Police Commissioner Danielle Outlaw said at a press conference that all of the victims were male.
The suspect was arrested in an alleyway without incident, the Outlaw said. He had a bulletproof vest, several magazines, an “AR rifle”, a handgun and a police scanner, she said.
“At this point, all we know is that this individual decided to leave their home and target individuals,” Outlaw said.
The shooting happened a day after gunfire erupted over a bank holiday weekend Block party in Baltimore, about 100 miles (160 kilometers) southwest, killing two people and injuring 28 others. According to authorities, those injured in the shooting ranged in age from 13 to 32, more than half of whom were minors.
The violence in Philadelphia marks the 29th mass murder in the country in 2023, according to a Database maintained by The Associated Press and USA Today in association with Northeastern University.
So far this year, the country has seen the highest number of mass killings and deaths in a single year.
According to the database, there have been more than 550 mass killings since 2006, killing at least 2,900 people and injuring at least 2,000 people.
