Three people were killed and 15 others injured in a mass shooting between two rival groups at an unsanctioned car show on Friday in the US state of New Mexico, according to local authorities.
The shooting took place at Young Park in the city of Las Cruces, about 22:00 local time.
Four people have been charged with in relation to the three murders, Las Cruces Police Department said on Sunday, including a 15-year-old boy.
Two 19-year-old men and one 16-year-old boy died in the shooting, police said.
In a statement on X, Las Cruces police said those arrested and charged were two 17-year-old boys, a 15-year-old boy and a 20-year-old man.
Police chief Jeremy Story said there had been”an altercation between two groups of people and that altercation escalated to gunfire between both groups”.
“Several other people were also injured in the crossfire.”
Mr Story said there had been “ill will” between the two groups prior to the car show.
About 50 to 60 bullet shell casings from handguns were found at the scene, police said, adding that the crime scene was huge and about 200 people had been at the park.
Police have asked any witnesses to come forward with information or video.
Those injured in the shooting ranged from ages 16 to 36. Authorities have not yet named any of the victims.
Seven patients were sent to nearby El Paso, Texas, which is just over the New Mexico border, for further medical treatment, said fire chief Michael Daniels.
Four other victims had been treated and released, Mr Daniels said.
