Los Angeles police are investigating the mysterious death of a 19-year-old man in Koreatown late last month. His family believes the death was the result of an assault.

Joon Hee Han was admitted to a Whittier hospital on July 25 to be treated for a head injury he apparently sustained in a fall, Los Angeles police said in a statement.

“According to family members, the fall was the result of an assault that occurred in the 700 block of South Harvard Boulevard in late July,” the LAPD said.

Investigators have not yet been able to confirm the family’s claim that Han’s death was the result of an attack, but are working to collect evidence and witness statements.

“As more information becomes available and the sequence of events leading to Joon Hee Han’s death becomes clear, we will provide more information,” police said. “Until then, we must refrain from further comment on this tragic incident until the facts are clear.”
