North Korea has detained a U.S. soldier from Wisconsin for crossing its borders without authorization.

After 23-year-old Travis King was released from a South Korean prison, he made his way to North Korea.

Here is what is known about King and the situation so far.

Who is private Travis King?

U.S. Army Pvt. 2nd Class Travis King is a 23-year-old cavalry scout with the 1st Armored Division. USA Today reported that King joined the Army in January 2021.

King graduated from Park High School in Racine in 2020, and has family who live in Racine, including his mother.

King’s maternal grandfather, Carl Gates, said his grandson joined the Army because he “wanted to do better for himself,” and he was drawn to service because he has a brother who is a police officer and a cousin in the Navy, the Milwaukee Journal Sentinel reported.

What happened to Travis King before he was detained in North Korea?

Prior to entering North Korea, King served a 47-day sentence in a South Korean prison for assault after he allegedly kicked and damaged a South Korean squad car.

King was released on July 10 and was due to be sent home to Fort Bliss, Texas. There, he could have faced additional military discipline and discharge from the service.

King’s stint in prison was not the first time he faced legal trouble in South Korea.

In February, a court fined him 5 million won ($3,950) after he was convicted of assaulting an unidentified person and damaging a police vehicle in Seoul last October, according to a transcript of the verdict obtained by The Associated Press.

The ruling said King had also been accused of punching a 23-year-old man at a Seoul nightclub, though the court dismissed that charge because the victim didn’t want King to be punished.

Not long after this photo was taken, Travis King, a U.S. soldier, bolted across the border and became the first known American detained in the North in nearly five years.

How did Travis King get into North Korea?

Upon his release from prison, King was escorted as far as customs but left the airport before boarding his plane. Instead, the following day, King joined a tour in the border village of Panmunjom, inside the heavily fortified Demilitarized Zone, which separates North and South Korea.
