Police in Michigan have said a teenage girl will likely be charged with murder after fatally stabbing a classmate over a boy they had both dated.
Detectives believe the 17-year-old suspect was “upset and disturbed” after breaking up with the male, who later started going out with 16-year-old victim Danyna Gibson.
Warren Police Commissioner William Dwyer said the older girl attacked Danyna while they were both in a classroom at Fitzgerald High School near Detroit, Michigan on Wednesday morning.
Neither were said to have had a history of trouble and were described as “straight-A students”, with the victim known to be on the school robotics team, the student council, and part of the school marching band.
She was stabbed twice in the chest and received treatment from a school resource officer, but later died in hospital.
“He’s taking it very hard that he wasn’t able to save her life,” said Mr Dwyer, who revealed that a steak knife had been recovered from the scene.
“This is truly a tragedy. This appears to be an altercation between two students and we’re investigating to determine why this occurred.”
One witness, Francesca Pascua, told The Detroit News that the incident happened during an economics class, with other students and a teacher present.
The 17-year-old said she “heard screaming” and fled because she thought the suspect “was going to stab everybody”.
Mr Dwyer said the girl was still in custody and would likely be charged with murder on Thursday, with Michigan prosecuting 17-year-olds as adults in homicide cases.
The boy believed to be at the centre of the incident is said to be cooperating with the police investigation.
The school remains closed for classes, but students and parents have been invited to come in for support and assistance from counsellors and psychologists.
School officials said they were conducting an internal review that will include safety procedures, with Mr Dwyer noting that no metal detectors were installed on the site.
In a statement on the Fitzgerald Public Schools’ website, Superintendent Laurie Fournier said: “Our hearts and prayers go out to the student’s family and we offer our deepest sympathy.”
