13 shot, stabbed, hit by vehicles at Syracuse, New York, block party, authorities say

At least 13 people were injured at a large pop-up block party in Syracuse, New York, early Sunday, police said.

Officers responded to a call of shots fired just after midnight and found a crowd of "hundreds" of people. People had been shot, stabbed, or struck by vehicles fleeing the scene, police said.

At least four people were shot, five were stabbed and four were hit by vehicles, according to information provided by police based on victims found at the scene or nearby hospital. The city's gunshot detection system showed dozens of rounds being fired, according to Syracuse Police Chief Joe Cecile.

Syracuse Police Lt. Matthew Malinowski said the 13 known victims included three males and 10 females, ranging between the ages of 17 and 25. They are all expected to survive.

Police found the victims on the street or later at hospitals, Malinowski said.

Cecile told Syracuse.com that the large crowd was a mix of high school students, recent high school graduates, and college students, who had mostly returned home for the summer.

Although the block party was advertised on social media, there was no permit issued, Cecile told the news site. He also said streets were not officially blocked off and had no police watching.

Police said those who were shot included a 22-year-old woman who was hit in the abdomen, a 17-year-old girl who sustained hip and midsection wounds, a 20-year-old woman who was struck in her right hip, and a 20-year-old man who was shot in his forearm.

Victims who were stabbed included a 25-year-old woman with multiple wounds to her shoulder and midsection, a 17-year-old girl with leg and arm cuts, a 19-year-old woman and a 17-year-old boy who both received cuts to their heads, and a 24-year-old woman with cuts to both legs, police said.

Those hit by vehicles suffered from cuts and abrasions, police said.

The "complex" investigation is active and ongoing, Malinowski said. He said there were no further updates on the conditions of the injured or the investigation Sunday night.

The mayor’s office did not immediately respond to request for comment.
