A young woman was shot and left to die outside her family's home in Fridley, officials said Friday.

Jayden L. Kline, 18, was taken by emergency responders to a nearby hospital, where she was declared dead Thursday afternoon, Anoka County Sheriff's Office spokeswoman Tierney Peters said.

Later in the evening, a 17-year-old boy was arrested in connection with Kline's death. His name is being withheld because he is a juvenile.

Fridley police and an Allina ambulance were dispatched shortly before 4 p.m. to the 4500 block of NE. 3rd Street regarding what initially was reported as a hit-and-run crash, Peters said.

Law enforcement "later determined that [Kline] had suffered a gunshot wound," a statement from Peters read.

Officials have yet to address a possible motive for the killing.

Cynthia Goren, who lives next door to the Klines, said she rushed out of her home when "we heard the noise, the bang" and initially thought it was a crash.

"I saw her on the ground while our neighbor was doing chest compressions," Goren said. "She had packages and a big drink in her hand."

Once Goren learned that her neighbor had been shot, she said, "We just didn't even think of that. ... It's just so terrible that [the suspect] had to get so angry to do something like that."

Kline graduated in June from Columbia Heights High School, where she was on the synchronized swim team.

"She was so very, very proud of that," Goren recalled. "It's so sad. One day they are there, and then they are not."
