Rebello returned to her California Avenue rental with her twin sister, Jessica, Jessica’s boyfriend, John Kourtessiss, and a third woman, Shannon Thomas of Connecticut, when the gunman knocked on their door at about 2:20 a.m.
Someone in the house peeked out a window to see who was there, and the burglar, wearing a ski mask, entered the house and held all four people at gunpoint.
He demanded cash and wasn’t happy with the amount they had, sources said.
“I saw you at the bar drinking. I know you have more money than this!” he snarled, according to a law-enforcement source.
The intruder released Thomas, telling her to go to a nearby ATM and bring back cash.
She drove to a nearby Bank of America branch and called 911.
She told police the man had a handgun trained on her friend’s head in the upstairs bedroom, according to police radio calls.
Cops scrambled to the scene, and they peered in and saw the gunman holding Andrea in a headlock, a law-enforcement source said.
At least one cop went in through the front door and the gunfire began.
