Kerby Revelus

Kerby Revelus, 23, used a kitchen knife to kill his sister Samantha, 17, a Milton High senior, and his 5-year-old sister Bianca. When police broke down the door to the upstairs apartment on Belvoir Road yesterday afternoon, they encountered an unimaginably gruesome scene: 23-year-old Kerby Revelus slashing the throat of his sister, who had been celebrating her fifth birthday.

Revelus then turned on his 9-year-old sister Sarafina with the same kitchen knife. Their 17-year-old sister Samantha had been stabbed to death. It was then, Police Chief Richard G. Wells Jr. told the Globe last night, that officers shot and killed Revelus - saving Sarafina's life.It was Sarafina who had called police after she was told to by her older sister.

"His intent was clear," Wells said. "He was trying his best to kill all of them."The sisters' mother, whom police did not name, was at work at the time of the attack. The father's whereabouts at the time was unknown. The girls' grandmother was in the basement doing laundry. Bianca's birthday cake, decorated with candles, sat on a table.
