Minnesota teenager Fenan Uso shoots dead ex girlfriend Jayden Lee Kline, 18, in his van while arguing on their way back from the mall before dumping her body in front of her house and speeding off

A Minnesota teen has been charged with second-degree murder, with police accusing him of fatally shooting his ex-girlfriend and throwing her body out of his van.

Fenan Uso, 17, and broke up with Jayden Lee Kline, 18, two weeks before the Dec. 21 shooting. The gruesome murder took place in the Minneapolis suburb of Fridley.

The emergency services were called around 4 p.m. to the report of an injured woman. When they arrived, they found Kline lying unconscious in her driveway.

She was rushed to a nearby hospital, where she was pronounced dead less than an hour later.

On Tuesday, a spokesperson for the Anoka County Prosecutor's Office confirmed that prosecutors are charging Uso as an adult.

The couple dated for about a year but recently broke up after the suspect was dishonest, the victim's family said.

According to the St. Paul Pioneer Press, Uso and Kline dated for about a year before breaking up. The breakup occurred because he had not been honest with his family about their relationship.

On the tragic day of her death, Kline and Uso were together at the Rosedale Center mall.

Neighbors said they heard a loud bang around 4 p.m. and then saw a gold van speeding away from Kline's home.

While her brother, Brandon, told police he saw her lying lifeless near their driveway shortly afterward. He told police his first reaction was that his sister had been hit by a car.

Police say a ring camera in the area showed Uso's van driving slowly toward Kline's home and then stopping. A shot is heard and moments later a woman fell out of the car.

Investigators were able to determine that the van belonged to Uso. It was in his mother's name. Cell phone records later tracked him to another Minneapolis suburb.

When he was taken into custody, police found a gun in the center console of his car.

When questioned, Uso admitted to having an argument with Kline and pulling the trigger moments after he dropped her off. He allegedly told officers that he “knew he had done something stupid.”

Police said the .40-caliber Smith & Wesson they recovered from his car matched a handgun stolen in Iowa. Uso said he acquired it the day before the shooting.

Kline was a graduate of Columbia Heights High School, where she was on the synchronized swimming team. At the time of her death, she was considering a career in nursing, friends say.

Zena Stenvik, the superintendent of Columbia Heights Schools, told ABC Minneapolis that the community is “reeling” after Kline's death

The suspect attended Fridley High School, where he was a star on the wrestling team.

Kline was a graduate of Columbia Heights High School, where she was on the synchronized swimming team. At the time of her death, she was considering a career in nursing, friends say.

'She was so very proud of that. It's so sad. One day they are there and the next they are not,” said her neighbor Cynthia Goren the Minneapolis Star-Tribune.

Zena Stenvik, the superintendent of Columbia Heights Schools, said ABC Minneapolis that the community is reeling after Kline's tragic death.

''The community is reeling. Just full of sadness and grief. A tough night last night, and a tough day today.”

Stenvik said Kline had been a mentor to younger athletes at the school and was proud of her Native American heritage.

“She was truly a balance of her native culture, her passion for that culture, and also a friend, a supporter and also an incredible athlete,” Stenvik added.

“We must put an end to this gun violence and the youth having guns in their hands. It's very problematic. Our youth is so vibrant. They have their whole lives ahead of them,” Stenvik also said.

It was Goren who told police that shortly before Kline's body was discovered, she heard a “noise” or a “bang.” At first she thought it was a car accident.

'I saw her lying on the floor while our neighbor was doing chest compressions. She had packages and a large drink in her hand.”

Goren said it never occurred to her that Kline had been shot.

'We just didn't even think about that… It's just so terrible that [the suspect] I had to get so angry to do something like that.'

Uso will make his first court appearance on January 5.
