Two toddlers and an infant were found dead inside a Phoenix home on Monday morning, but the circumstances surrounding their deaths remained a mystery, authorities said.
The victims were described as a 3-year-old boy, a 2-year-old girl and a 7-month-old girl, the Phoenix Police Department said in a written statement.
“There are no obvious signs of trauma to the children and so investigators will interview the parents as they try to piece together what caused this tragedy,” the police statement said.
All three children were “unresponsive” after rescuers responded to a 911 call from the home in the area of 24th Street and Baseline Road about 7:30 a.m., police said.
“They attempted CPR but were unable to revive the children,” according to the statement. “Phoenix Fire pronounced all three kids dead at the scene.”
The children’s parents, as well as another adult relative, were at the home at the time, officials said.
No further details were available.
