(CNN) -- A Brooklyn apartment turned into a grisly scene of carnage Saturday night when a mother and her four children were stabbed to death, New York police said.
The stabbings took place in the Sunset Park neighborhood of Brooklyn, New York Fire Department spokesman Jim Long said. It was not immediately clear what led to the stabbings. All of the victims lived at the Brooklyn home.
All five of the dead had stab wounds to their upper bodies, police said. Police identified the victims as Qiao Zhen Li, 37; Linda Zhuo, 9; Amy Zhuo, 7; Kevin Zhuo, 5; and William Zhuo, 1.
One man has been taken into custody, but no official charges have been filed, Officer Christopher Pisano said. Police spokesman Sgt. Thomas Antonetti said police haven't confirmed the relationship of the person in custody to the victims.
