The 30-year-old followed the sisters, Jessica and Andrea, Jessica's boyfriend John Kourtessiss and another student called Shannon Thomas back to the girls' California Avenue sorority house from the popular student bar, McHebes, according to the New York Post. The gunman reportedly targeted the students after seeing them spending large amounts of money in the drinking spot to celebrate the end of the school term. Around 2.20am he peered through the window in his ski mask and knocked on the door before forcing himself in and taking the group hostage. Raiding the home he shouted: 'I saw you at the bar drinking. I know you have more money than this!', according to police sources quoted in the Post report. He made the twins remain but told Thomas to leave and withdraw money from an ATM machine - warning her he would shoot her friends if she tried anything. While away from the home she called 911. As police arrived neighbors said they heard blood-curdling screams and what sounded like a woman pleading for her life. Victoria Dehel, who lives four doors down told the New York Times that she heard shouting. 'I turned to my boyfriend and I said, 'I think someone just got murdered'. '[Police] drew their weapons and went inside,' neighbor Frank Pugliese, 19 told the Post. She was pleading for her life. You could tell she was scared. It was a surreal moment . . . She was pleading - her voice was trembling and she yelled, "No, no!" " Smith is believed to have held them on the second floor. Thomas told the 911 dispatcher that he had a silver handgun pointed at her friend's head in a bedroom, NBC reported. Anthony Kourtessiss said his son was being questioned by police last night and Jessica was 'inconsolable'. 'It's a terrible situation,' he told the Post. [Jessica] was very upset, inconsolable right now. Rebello was a member of the Beta Sigma Phi sorority and lived with six of her sorority sisters at the home including her sister. A private vigil was held at the Hofstra Student Center last night and it was announced today that her funeral will take place on Wednesday. Rebello's father, Fernando, was too distraught to discuss the incident outside the family's Tarrytown, New York yesterday. 'It's my daughter, my baby daughter,' the landscaping company chief told the Journal News outside the home he shares with wife Nella. She was so beautiful. I'm so confused.' 'I don't know what to do,' he added. Her godmother told the newspaper: 'It's just too tragic'. Andrea was a junior at Hofstra studying Public Relations and Sociology and had attended Sleepy Hollow High School alongside her sister. 'I'm 100% Portuguese and have an identical twin sister so I guess that makes me kind of unique?' she wrote on her blog. Principal Carol Conklin-Spillane said the girls were 'a set' and Andrea was devoted to her family who are close to other members of the Portuguese community who live in the area. 'She had a devotion to family and sense of purpose and of opportunity,' she said. Neighbors said their house had a vegetable garden and the twins would sometimes drop off the produce. They brought me some vegetables from their garden. They're very nice people. They'd do anything for you,' Harris Bank told the New York Post. Her funeral will be held at St. Teresa of Avila Church in Sleepy Hollow and will be officiated by the Rev. Osvaldo Franklin, of Our Lady of Fatima in Yonkers, who gave the twins their first communion. He said they helped with Mass for several years after that. Authorities said Andrea's twin sister is now with their family. 'I ran outside and police officers were like, 'go back inside your house, go back inside your house'.' Friends said the girls at the house, including the twins, had been out celebrating the end of the school year earlier that evening. They went to a popular university bar, McHebes. The bar was really crowded, and all the sisters were there. They were [going] all-out because it's the end of school,' Amanda Babyatsky, 22 told the Post.
