A high school senior was shot and killed in an apparent murder-suicide by her older DJ boyfriend as they headed to her homecoming dance in Louisiana, officials said.
Dashayla Ardoin, 17, and Glenkeithan Robertson, 21, were found dead with gunshot wounds in a car en route to Mamou just after 7pm on Saturday, the Acadia Parish Sheriff’s Office said.
“From the investigation, this case is believed to be a murder/suicide,” the sheriff’s office said.
Authorities believe Robertson was the shooter, although they do not yet know a motive behind the killings. Sheriff KP Gibson told PEOPLE.
They were reportedly on their way to Ardoin’s homecoming dance at Mamou High School, Gibson added.
There were no other occupants in the vehicle at the time and no one else was injured, the sheriff’s office said.
In a moving tribute on Facebook, Ardoin’s high school noted that they would return to class the following day “without one of our own.”
“Dashayla will always be remembered for her courage and bravery, her kind heart and her beautiful smile. She was so much loved and will be greatly missed,” the high school said wrote.
Robertson’s social media shows he worked as a DJ. A photo of him and Ardoin on his Instagram was captioned “Me & You Against The World.”
The case is still under investigation.
