Reports from multiple Los Angeles news outlets indicate that Dojoon Park, the owner of DJ General Tool and Wire who was arrested for running a cargo theft ring, is a resident of Montebello, California.
While this suggests he is a resident of the United States, his nationality has not been specified in available reporting.
The news coverage focuses on the criminal investigation and his residency in the Los Angeles area:
News outlets consistently identify the suspect as Dojoon Park of Montebello, California, arrested in connection with a large-scale hardware theft operation.
Nationality not mentioned: No reports explicitly state that he is an American citizen. Residency does not guarantee citizenship.
Other search results mention a Korean singer also named Dojoon Park, but this is a separate person and not related to the cargo theft case.
He appears to be bi-racial which certainly argues for him being born in the USA, but that might not be so of course.
I went to school with a gal whose mom & dad married in post WWII Japan, her dad was African-American and her mother was Japanese. She was a very nice girl, but complained A LOT about how strict her mom was. Her mother would not let her wear anything red, that was the first step on the road to perdition in mom’s mind.
