His friend Patrick Park, who he was travelling with, stood by in vigil, in shock.
The two were swimming in the lake when, suddenly, Jinwoo stopped.
“I don’t know why, but he stopped,” his friend told the Herald. “He’s a way better swimmer than I am. We got discharged from the Navy a couple of months ago.
“I thought something was wrong because he didn’t reply when I talked to him. I called for help. I tried to get him but I couldn’t ... and he just sank and never came up,” he recalled.
“He just disappeared, I don’t know what happened to him.”
The two arrived in Wānaka from Te Anau about 2pm on Thursday. Jinwoo, also known as Mark Park, was keen on a pie and a swim so they got pies from the bakery on the lakefront and, after a nap, they went for a swim.
Patrick spent the night in his car on the lakefront, awaiting any news, any possible sighting of his friend.
“I can’t believe this happened.”
Patrick has given the tragic news to the 22-year-old’s parents in South Korea. He said the family were planning to come to New Zealand as soon as possible.
In a statement, police said that “while formal identification is yet to be completed, Police believe it is the body of the swimmer who was reported missing at around 6:30pm on Thursday, after failing to resurface”.
“Police extends its condolences to the person’s family and loved ones.Police are making enquires in relation to the death on behalf of the Coroner, who will release their findings in due course.”
