Four members of a family of Indian descent, including two boys, were shot dead in their home in West Des Moines, United States.
The incident occurred Saturday morning. The family members were identified as Chandrasekhar Sunkara, 44; Lavanya Sunkara, 41; and two boys aged 15 and 10, CNN said.
The police found several shots on the body of the victim.
The case was cleared up after the guests who were staying at the victims' residence saw the bodies and informed the local authorities.
"We are continuing our work as part of this investigation, and we will continue until we have answered as many questions as the evidence allows," said Sergeant Dan Wade of the West Des Moines Police Department.
A motive behind the murders remains uncertain. No suspects have been identified.
