A Mexican musician and several family members were shot dead in Mexico City. The family dog was also murdered during the attack.
A six-year-old son of the family was found alive and unharmed, being the only person to survive the incident.
Two of the victims were tied up at the time of the attack, as was the family's pet, which suggests the victims were subdued before being killed.
Two suspected men were detained by authorities in connection with the crime.
