NORTHBORO, MASS. (WHDH) - Three men appeared in court Monday, one day after their arrest in connection with a deadly shooting at a house party in Northboro. 

The shooting happened near 1:25 a.m. Sunday on Howard Street. 

On Monday, court officers hustled Wallisom Texeira Da Silva, Arnoldo Nogueira Filho and Pedro Desouza-Passos into court one-by-one to face weapons charges. 

Officials at a press conference on Sunday said a partygoer first flagged down an officer near 1 a.m. to report someone with a gun in the home. 

While police were assembling and preparing to enter the house, Worcester County District Attorney Joseph Early said, “they heard multiple gunshots.”

Officers went inside, officials said, and found a 16-year-old and a 17-year-old with gunshot wounds. The 16-year-old, later identified as a Bellingham resident, was pronounced dead at a hospital. The 17-year-old’s injuries were deemed non-life-threatening. 

In court, prosecutors said Da Silva, Filho and Desouza-Passos were all occupants in a car stopped by investigators after the shooting. 

Prosecutors said investigators found ammunition in two purses in the car. Prosecutors said investigators also found a gun that one of the suspects admitted was his. 

While prosecutors laid out their case, friends of the suspect who came to court in Westborough told 7NEWS the trio were not involved in the murder of the 16-year-old. 

“He’s a hardworking guy,” one person said. “And he was at the wrong place at the wrong time.”

Officials on Sunday described a “chaotic” scene as emergency crews responded, with well over 200 people on the property. 

Come Monday morning, SKY7-HD spotted officials still searching for evidence and sifting through the debris of the party. 

At Northboro police headquarters, investigators were busy interviewing witnesses, with several witnesses seen coming and going throughout the day.

“It’s scary,” said area resident Beth Rutman when asked her thoughts about Sunday’s events. 

“There are no safe places anymore, really,” said fellow area resident Constance McManus. 

Speaking with 7NEWS, neighbors said large gatherings are nothing new at the home where the shooting happened. 

“It usually begins around 12:30 and we see 50-plus cars pulling in and then it comes in increments,” one person said. “So, around 2:30 you’ll see hundreds more cars streaming up there.” 

Bellingham police in a joint statement with the Bellingham Public Schools Sunday said they were aware of the shooting. 

Though the teen who died was identified as a Bellingham resident, authorities said he was not a student at the Bellingham Public Schools. 

“We are also aware that other young people from Bellingham were in attendance at the party where the shooting occurred,” officials said. 

The police and the school district said officials had been in close contact with investigators in Northborough and said there was no threat to anyone in Bellingham. 

Still, “out of an abundance of caution,” officials said there would be an increased police presence at Bellingham High School in the coming days. 

Officials said the high school would also have guidance staff available “to speak with anyone affected by this tragic incident.”

Back in Northborough, local authorities have asked that anyone with video or any other information related to the shooting contact the Northboro Police Department. 

The three people facing weapons charges remained behind bars as of Monday afternoon, after their arraignment. 

With their investigation still ongoing, police would not say whether they intend to charge the owner of the property where the shooting took place.
