CIUDAD JUAREZ, Mexico - Mexican police found Sunday a family of eight, including three children, stabbed to death and tied down in their home in the northern city of Ciudad Juarez.
A two-year-old boy survived the attack and was handed to neighbours, local police said.
The Chihuahua state prosecutor's office said the assailants apparently forced their way inside the house and killed two men, three women and three children between the ages of four and six.
Their mouths were covered with duct tape and their hands and feet were tied. Neighbors said they heard gun shots but authorities said the victims had stab wounds.
Neighbors said the house owner was a car salesman.
The family was supposed to attend a meeting of Jehovah's Witnesses when they were attacked inside their home on Sunday morning, according to testimonies.
They were discovered dead after members of the congregation went to look for them.
Ciudad Juarez, which borders the US state of Texas, was once the deadliest city in Mexico amid a turf war between drug cartels.
More than 10,000 people have been killed in the city since 2006 but the murder rate began to decline in 2011.
Local officials say the drop in violence is due to tougher policing and crime prevention programs, but security experts believe it began to wane after the Sinaloa drug cartel defeated the rival Juarez gang.
