The Nebraska State Patrol said the investigation into the death of a Norfolk singer early Sunday is ongoing.
Spokesman Cody Thomas said he couldn't release any more information after the Journal Star asked a number of questions regarding the incident Monday.
Abby Uecker, known by her stage name Abby Nicole, performed Friday and Saturday at the Thayer County Fair in Deshler.
She was injured about 4:20 a.m. while riding inside a utility vehicle near the racetrack on the fairgrounds, Thomas said. Uecker, 25, was taken to Thayer County Hospital in Hebron, where she died at 5:30 a.m.
The state patrol declined to say how her injuries occurred, why she was in the vehicle or whom she was with.
Thayer County Attorney Daniel Werner said he won't release any additional information until the investigation is completed.
Uecker is a country musician who performed with her band County Road.
According to her website, Uecker has performed since she was 4 years old and majored in theater performance at the University of Nebraska-Lincoln. While in college, she joined County Road and co-wrote songs with writers in Nashville, Tennessee.
In 2014, Uecker was diagnosed with a brain tumor after experiencing severe headaches and underwent surgery. She returned to school in 2015 and started singing again. She released her first single, "Cool," last year.
Bandmate Chad Barnhill said on his Facebook page that Uecker "touched so many lives," especially his own.
A candlelight vigil for Uecker was planned for Monday evening at Skyview Lake, according to Brittnay Dawson, of the Norfolk Area Chamber of Commerce.
"She was a friend, a daughter, a sister, an aunt, a performer, an artist, a true role model and incredible inspiration for many. Our hearts are all filled with tremendous sorrow, and we can lean on each other during this difficult time," Dawson said on Facebook. "Abby was always living for the moment, and tonight we want to make that moment about her and celebrate all the love she gave to this world through herself and her music."
