Son Jung Min's father reminds us that it's still super sus that Mister A was found with his son's phone the morning after the two went to the Banpo Han River Park where his son went missing and only Mister A survived the night. The critical question is whether Mr. A took SJM's phone before or after 3:37 AM. Why? At 3:37AM, Mr. A called his parents. Had he taken the phone after 3:37AM, it would mean Mr. A went back down to the riverbank or actually into the river to take it off of his friend's body and abandon him before heading home like nothing had happened.
