(NEW YORK) -- A family barbecue, a park gathering and a nightclub were among the settings for at least nine mass shootings that broke out across the country between Friday and early Monday, marking the fourth consecutive weekend U.S. law enforcement officers have responded to multiple incidents, each involving four or more victims shot.
The shootings this weekend have left at least six people dead and 42 injured in nine cities, according to the Gun Violence Archive, a site that tracks shootings across the country. The website defines a mass shooting as a single incident involving four or more victims, which differs from the FBI's definition as a single incident in which four or more people, not including the suspect, are killed.
The string of consecutive weekend mass-casualty incidents began over the Memorial Day holiday, when at least 17 shootings left a total of 13 dead and 79 injured in cities across the country. The three-day holiday was followed by a weekend that saw at least 11 mass-casualty shootings that left 17 dead and 62 injured across the nation.
Last weekend, at least 10 mass-casualty shootings nationwide killed 10 people and injured 42.
The string of deadly weekends comes in the wake of a May 14 mass shooting at a Buffalo, New York, supermarket that left 10 people dead and three wounded and the May 24 massacre at Robb Elementary School in Uvalde, Texas, that left 19 students and two teachers dead.
As of Monday, there have been 277 mass shootings in the U.S. this year, according to Gun Violence Archive.
1 killed, 8 injured in East Harlem, New York
Gunfire erupted early Monday at a park in the East Harlem neighborhood of New York City, where police said a group of people were having a barbecue when multiple shooters opened fire.
A 21-year-old man -- identified as Darius Lee, a former New York high school basketball standout and college player -- was fatally shot, according to ABC New York station WABC. The New York Police Department said six additional men and two women suffered non-life-threatening wounds in the barrage of gunfire that broke out along the city's East River at about 12:35 a.m.
Authorities believe multiple guns were used in the shooting based on the shell casings homicide detectives found at the scene. Police said one handgun was also recovered from the scene.
No arrests were immediately announced and a motive remains under investigation, although authorities said they suspect the shooting was gang-related.
Lee was a member of the Houston Baptist University basketball team.
“The loss of anyone in the HBU family is a cause for grief, but it’s especially painful when we see the death of a student, particularly when so much promise is cut off in such a violent, senseless way. We offer our prayers for Darius’s family and closest friends," HBU President Robert B. Sloan wrote in a post on Twitter.
