A 20-year-old man is accused flying across the country and trying to murder someone with whom he had an online gaming dispute in a hammer attack.

Edward Kang, 20, flew from Newark, New Jersey, to Jacksonville, Florida, to confront someone he had an online dispute with, Nassau County, New Jersey, Sheriff Bill Leeper said. Court records show he was charged Monday with second-degree attempted murder and attempted burglary.

A preliminary investigation indicates Kang knew the victim only online, having met him playing a fantasy video game called ArcheAge. According to the game’s website, it is shutting down its North America and European servers this week because of a declining number of users.

Leeper did not detail the substance of the dispute with the victim, who Leeper said is “around the same age” as Kang.

Investigators say Kang told his family he was flying to visit a friend he met years ago. Leeper said they were able to determine that he took an Uber ride from the Jacksonville airport to a hotel in Fernandina Beach on Friday.
