Five members of a family have been found stabbed to death in their home in Oklahoma and two teenage relatives are in custody.
Officers were called to a home in Tulsa late on Wednesday and found five people dead from stab wounds, according to Sgt Thomas Cooper of Broken Arrow police.
A 13-year-old girl who was wounded underwent surgery today and is now said to be in a serious but stable condition.
Another child, a girl aged two, in the home was not harmed and is being cared for.
Sgt Cooper said the suspects are males aged 16 and 18 who are related to the victims.
He said they fled the home before police arrived but a tracking dog trailed them.
Authorities say the victims were found following an “open 911” call in which someone dialled 911 but did not speak. The call was then traced to the home.
Sgt Cooper said the victims include adults and children but he did not detail how they are related.
He said an investigation of the home could take all day and the Oklahoma Bureau of Investigation is assisting.
