A heavily armed gunman in a bulletproof vest opened fire on the streets of Philadelphia, seemingly at a random, killing five people and hurting two boys before surrendering, police said.
The shootings took place over several city blocks in the southwestern neighbourhood of Kingsessing on Monday night.
Responding officers chased the suspect as he continued to fire and he was arrested in an alleyway after giving himself up, police commissioner Danielle Outlaw said.
“Thank God our officers were on the scene and responded as quickly as they did. I can’t even describe the level of bravery and courage that was shown, in addition to the restraint that was shown here,” Ms Outlaw said.
No connection was immediately known between the victims and the gunman, she said.
He had a bulletproof vest, an “AR-type rifle”, multiple magazines, a handgun and a police scanner.
Officers were flagged down at about 8.30pm and multiple calls of shots fired came in from Kingsessing.
Police found some gunshot victims and, as they were attending to them, they heard more gunfire, Ms Outlaw said.
Police later told Fox 29 a fifth victim was found.
He was chased into his home and shot to death.
Bullet casings were found outside the home.
The suspected gunman was identified as a 40-year-old.
A second person was also taken into custody who may have returned fire at the suspect, but police did not know whether there was a connection between the two people, Ms Outlaw said.
The chief said dozens of shell casings were found across an eight-block area.
“You can see there are several scenes out here,” Ms Outlaw said.
“We’re canvassing the area to get as much as we can, to identify witnesses, to identify where cameras are located and to do everything to figure out the why,” she said.
Three of the dead were 20 to 59 years old, while the fourth, who had not yet been identified, was estimated to be between 16 and 21.
The victim found in his home was 31 years old.
All were male.
The two victims admitted to hospitals are boys aged two and 13.
They were in stable condition, Ms Outlaw said.
The shooting occurred within hours of a fatal shooting that erupted at a neighbourhood festival in Fort Worth, Texas, leaving three people dead and eight injured.
A day earlier, two people were killed and 28 others were wounded in a shooting at a holiday weekend block party in Baltimore, about 90 miles to the south west. More than half of the victims were minors, officials said.
The wounded in that shooting ranged in age from 13 to 32, with more than half children, according to officials.
The Philadelphia violence is the country’s 29th mass killing in 2023, according to a database maintained by the Associated Press and USA Today in partnership with Northeastern University – the highest on record by this time in the year.
The numbers people killed in such events is also the highest by this time in the year.
There have been more than 550 mass killings since 2006, according to the database, in which at least 2,900 people have died and at least 2,000 people have been hurt.
