As students filed into Jersey City schools Thursday morning, two of their classmates were missing after a rare triple homicide overnight that the mayor called an incident of domestic violence.

A 31-year-old man is charged with three counts of first-degree murder and other crimes for allegedly stabbing a woman and her two young children to death in their Jersey City apartment, investigators said Friday.

A Jersey City man accused of killing a woman and her young children before stabbing himself encountered at least two witnesses, court documents claim.
