A state prosecutor in Mexico says the fatal stabbing of eight family members in the border city of Ciudad Juarez was likely perpetrated by someone they knew.
Chihuahua state Prosecutor Enrique Villareal says there was no forced entry into the house where the bodies were found Sunday morning.
He said Monday that the knife used in the crime may have come from the kitchen.
All the victims had tape over their mouths and their hands were tied, including two 4-year-olds and a 6-year-old. A 3-month-old baby survived the massacre.
Officials say organized crime was not involved. State authorities are offering 300,000 pesos ($23,000) for information about the assailants.
Warring drug cartels once made Ciudad Juarez one of the deadliest cities in the world, but killings have declined in recent years.
