TAOS, N.M. (AP) — A New Mexico EMT responded to the scene of the crash that killed his 16-year-old daughter, unaware that she was involved.

Maria Elena Cruz, 16, was killed in a three-vehicle crash that authorities say was caused by country singer Kylie Rae Harris. Harris was also killed in the crash, KRQE reported.

Taos County Sheriff Jerry Hogrefe told the Taos News that investigators believe Harris caused Wednesday’s crash and that speed appeared to be a contributing factor when she clipped the back of another vehicle, sending her into oncoming traffic. She then crashed head-on into an SUV driven by Maria Elena Cruz.

Harris and the Taos High School student died at the scene. The responding emergency crew included the teen’s father, Pedro Cruz, the deputy chief of the San Cristobal Volunteer Fire Department.

“He’s also an EMT, so he’s no stranger to going out on calls both medical, crashes and other things, but very traumatic for him to not know but to respond anyway and then find it was his family member,” said Hogrefe.

“At this time, I will say with most certainty that Miss Cruz was an innocent victim of this senseless crash caused by Ms. Harris,” the sheriff said.

Authorities also have said evidence at the crash scene indicated alcohol may have been involved, though they declined to provide details. They were awaiting a toxicology report from the coroner’s office.

The Taos News reported that Harris, 30, had a prior DWI conviction in Collin County, Texas, in 2017 and had been ordered to install an ignition interlock device on her vehicle, according to court records.

A single mother, Harris was in Taos to perform at an annual music festival. She had posted on social media earlier that day that she was low on gas and 36 miles (58 kilometers) from the nearest gas station. “Dear baby Jesus please don’t let me get stranded in NM,” she tweeted.

Harris’ publicist, Sarah Frost, said Thursday the musician’s family and friends were heartbroken over her death. Harris released a self-titled album earlier this year and had spent the summer traveling to shows throughout Texas.

Students and faculty at Taos High were in shock after learning that Cruz was killed in the crash. The sophomore was remembered as beautiful, kind, hardworking, intelligent and inspirational.

Taos County Fire Manager Mike Cordova said in an email that the Cruz family was reeling from her death. The community of San Cristobal was holding a fundraising dinner Friday to help the family with funeral costs.
