A fella’s misdirected anger and frustration ended with one of his sisters (L) stabbed to death and the other decapitated. A brave litte girl (R) had the courage to call the police to end the mayhem:

In a shocking killing spree, a 23-year-old man stabbed his 17-year-old sister to death and then decapitated his 5-year-old sister — during the younger girl’s birthday party Saturday in Milton, Mass. Cops shot and killed the man, identified as Kerby Revelus, as he moved toward a third sister, who was wounded. Here, police comfort a distraught woman outside the home on Saturday.

Responding officers broke down the door and shot him dead. The first one inside had witnessed Bianca’s beheading.
Sarafina was hospitalized Sunday with defensive wounds to her hands and stab wounds in her abdomen and one of her legs.
“In policing, we see the raw human emotion every day, but to think that a human being could afflict such an atrocious, violent act on his own family is unbelievable,” Milton police Chief Richard G. Wells Jr. said Sunday. “When I walked up to the first officer (on the scene), I could see the whole story right in his face. This just told me that this was something very bad.”

Investigators believe Revelus had been agitated since Friday night, when he got in a fistfight with a neighbor in this tony suburb that is also home to Massachusetts Gov. Deval Patrick. Revelus, investigators believe, may have targeted Samantha in the fallout from the episode.

“Blows were exchanged,” Wells said. “I don’t know the cause of it, but we’re confident that did happen. He had been agitated in the hours that followed that, going into the day and last night.”

Investigators believe Revelus attacked his siblings with a household knife while their grandmother, who neighbors say lives on the first floor, was doing laundry in the basement. The children’s parents were away; their mother is a nurse at a Boston hospital, Wells said.

Sarafina, a student at the Tucker Elementary School, just behind the house, called 911 just before 5 p.m. An officer on patrol in the neighborhood arrived within a minute, Wells said, and could hear an altercation inside as he reached the second floor. The 911 operator tried to persuade Sarafina to open the door, but when she didn’t the officer broke through

“As the officer entered the door, (Revelus) decapitated (Bianca) in front of him,” Wells said. “He actually walked into a killing field. He walked into such carnage, as far as the atrocity of it, I’ve never seen it.”

Within moments, four officers were inside and two of them shot Revelus as he tried to get to Sarafina, Wells said. Revelus fell, still clutching the knife.
