"She's inside, she's shot," the brother told detectives, according to an affidavit.

Investigators found 21-year-old Omelly Dominguez dead, slumped over the couch. She had been shot in the head behind her left ear.

The younger brother told police he heard the sisters arguing over money just before the gunshot, according to court documents. Omelly Dominguez had refused to give her older sister cash for a hotel, Daily Voice reported.

When he heard the shot, the brother walked into the living room. Angielly Dominguez "stared at him" then walked out of the home.

Court documents state Ring doorbell video footage caught her fleeing the scene just before police arrived at about 4 p.m.

Within hours, state police arrested Angielly Dominguez, of Jacksonville, Florida, driving southbound on the New Jersey Turnpike. The older sister had made it as far as Cherry Hill, but a state trooper easily spotter the white 1995 Ford Mustang with Florida license plates.

The trooper found five handguns in the car's trunk, according to an affidavit.

Meantime, Angielly Dominguez got engaged last month. Her fiance did not respond to inquiries from New Jersey 101.5.

Police noted in the affidavit the fiance attempted to report Angielly Dominguez to authorities in Jacksonville, Florida. Documents stated she took "all of his firearms and his vehicle."

Omelly Dominguez was set to graduate from William Paterson University's nursing program next year. She worked as an administrative assistant at the university.

The Bergen County Prosecutor's Office said Angielly Dominguez has been remanded to Bergen County Jail. She faces first-degree murder and firearm possession charges.
