An 18-year-old from Long Island is officially in police custody, accused of shooting into a crowd of college students who gathered for a house party over a week ago, killing a Bronx student.

Nassau County police announced the arrest of Jacob Mcmillan, 18, and charged him with murder, attempted murder, two counts of criminal possession of a weapon and burglary from a separate incident back in September.

On Saturday, Nov. 22, just before 11 p.m., Nassau County police rushed to the intersection of Willow and Kennedy avenues in Hempstead after a Shot Spotter notification went off. Amira McCleod, 19, died at the scene after trying to run once she heard the shots go off.

Nassau police said Mcmillan arrived at the party around 11 p.m. on Saturday, Nov. 22 with several friends and got into a verbal altercation with the party's host. Investigators said the host wanted to ensure no one brought a weapon inside the home.

"The suspect backs away from a group of people and begins to shoot a handgun," Nassau County Police Det. Lt. George Darienzo said. "Three shots are fired in total. Three people are struck with bullets. One fatal."

McCleod was a sophomore at Monroe University in The Bronx and was from Queens. She was a member of the women's college basketball program and was studying business, according to her biography on the school's athletics website. She had dreams of opening up her own clothing and sneaker store.

Her coach, Damel Ling, says this act of violence stole a life too soon.

"She had her whole life, her whole future ahead of her and for something like this to happen it's a senseless act that didn't need to happen."

The day after her death, the school released a statement that said in part: "The Monroe University community is devastated by the tragic loss of student Amira McCleod, a cherished member of our Express women's basketball team. We extend our deepest and most heartfelt condolences to Amira's family, friends, and all who knew and loved her."

Mcmillian is expected to face a judge for his arraignment Wednesday.
