But what began as a birthday bash quickly turned into a nightmare when a gunman opened fire, as reported by Need To Know.
One person was killed at the scene, near Morgan Hill, California, while six others suffered gunshot wounds in the horror, according to the Santa Clara County Sheriff’s Office.
The victim has since been identified by his family as 18-year-old Desiderio “Desi” Romero V, who was also known as “Pepper”.
Loved ones described him as a cherished son, brother, grandson, cousin and friend, while a fundraiser said he had been taken from them “far too soon”.
NateDeBaiits appeared to confirm the victim was his friend and former classmate in a series of emotional social media posts.
He wrote: “My deepest condolences to his family and everyone who loved him. This doesn’t even feel real.”
The streamer also asked followers to keep those who were injured and remained in hospital in their prayers.
In another post, he said: “This is one of the hardest things I’ve ever had to post.”
He insisted he was not posting for attention or sympathy, but because “someone I called a friend/classmate lost his life at my party”.
The streamer later said the violence had been completely out of his control and revealed he planned to leave San Jose after receiving death threats.
The shooting happened on Saturday night in an open field near Hale Avenue and Miramonte Avenue, in an unincorporated area outside Morgan Hill.
Deputies were initially called at around 10.15pm following reports of intoxicated people in the street and someone throwing bottles at cars.
But by the time officers arrived, hundreds of partygoers were fleeing the scene after gunshots had rung out.
The event had been promoted on social media and was described by the sheriff’s office as an “unsanctioned” or “pop-up” party.
Authorities said the exact location had only been shared hours before the event and around 300 people turned up to the field.
Santa Clara County Sheriff’s Office spokesperson Brooks Jarosz said deputies arrived to find “hundreds of people” running from the scene.
The sheriff’s office initially reported that eight people had been shot, before revising the figure to seven victims in total – one killed and six injured.
A handgun is believed to have been used and investigators have described the shooting as an isolated incident.
No arrests had been announced as of July 30, with detectives continuing to search for the person responsible.
Sheriff Robert Jonsen condemned the violence and said investigators would work “until those responsible for this horrific act are identified, apprehended, and held fully accountable”.
The sheriff’s office has described the investigation as lengthy and complex and appealed for anyone with information, footage or knowledge of the party to come forward.
Several victims were taken to hospital, with injuries reported to include wounds to the shoulder, abdomen and ankle.
Some of those injured were later discharged, while others initially remained in hospital.
Meanwhile, emotional tributes have poured in for Desi, with friends remembering the teenager as a much-loved member of his community.
His family said he was an aspiring carpenter who was preparing to begin his senior year at high school.
A GoFundMe set up to help with funeral expenses has raised tens of thousands of dollars following his death.
The shocking scenes were captured during a livestream of the party, with footage showing the atmosphere suddenly changing as the sound of gunfire sent people running.
The investigation remains ongoing.
