NEW YORK — A man was arrested Sunday on five counts of murder in the deaths of his cousin’s wife and her four children in a stabbing rampage in their Brooklyn home.
The suspect, 25-year-old Mingdong Chen, implicated himself in the stabbings late Saturday in the Sunset Park neighborhood, police said. Chief of Department Phil Banks said the victims were stabbed repeatedly with a kitchen knife.
Two girls, 9-year-old Linda Zhuo and 7-year-old Amy Zhuo, were pronounced dead at the scene, along with the youngest child, 1-year-old William Zhuo.
Their brother, 5-year-old Kevin Zhuo, and 37-year-old mother, Qiao Zhen Li, were taken to hospitals, where they also were pronounced dead.
Chen is a cousin of the children’s father and had been staying at the home for the past week or so, Banks said. He came to the United States from China in 2004 and seemingly struggled to make it, Banks said.
On Saturday night, Chen had apparently been acting in such a way that concerned Li, Banks said. She tried to call her husband, who wasn’t home, but couldn’t reach him.
Banks said Li called her mother-in-law in China, who also was unsuccessful in reaching her son. The mother-in-law reached out to her daughter, who lives in the neighborhood, Banks said.
She and her husband came to the house and banged on the door, then called 911. Officers in the area investigating another matter responded, Banks said.
‘‘It’s a scene you’ll never forget,’’ he said. The victims had wounds in their necks and torsos.
Chen was in custody and wasn’t immediately available to comment. He also faces counts of assault on a police officer, which happened while he was being processed, and resisting arrest, Banks said.
Bob Madden, who lives nearby, was out walking his dog when he saw a man being escorted from the building by police.
He was barefoot, wearing jeans, and ‘‘he was staring, he was expressionless,’’ Madden said.
