According to investigators, a 12-year-old Oklahoma girl killed her younger brother by stabbing him in the night on Thursday.
According to authorities, the young girl allegedly told her parents she had stabbed her 9-year-old brother just before midnight at their Tulsa home.
The youngster was given CPR by emergency personnel at the River Bank Plaza Apartments before being sent to the hospital, where he underwent surgery right after.
According to authorities, the 9-year-old passed away just after 2:30 a.m.
The boy’s sister was arrested and is being held at the Family Center for Juvenile Justice.
Police have not revealed a motive for the tragic killing, stating it will be the court’s burden to uncover intent.
“Obviously we did some interviews, but interviews with a 12-year-old are very preliminary,”
