Ganghwa Island shooting
The Ganghwa Island shooting occurred on July 4, 2011 at 11:50 a.m. at a coastal base in Ganghwa County when a South Korean marine corporal identified Kim Minchan assigned to the South Korean 2nd Marine Division went on a shooting spree towards his team with a K-2 rifle and later attempted a suicide with a grenade. The assault was carried out in a barracks, killing four soldiers while injuring another. Three were killed on the spot while the fourth died after being taken to the hospital. One of the fatalities was an officer while the rest were rank-and-file soldiers. The victims included the cousin of South Korean actor, Im Hyeok-pil.

Perpetrator: Kim Minchan, Corporal (19)
Accomplice: Jung Joonhyeok (20)

Issues
The South Korean marine corps formed a task force to investigate the rampage. This came amid claims of sexual harassment, hazing, extortion in the hierarchies, and violence that are happening within the South Korean marine corps' barracks. The problems have been happening for years and they were blamed for the recurring shooting incidents. In June 2005, for instance, a young soldier threw a grenade and fired at his sleeping teammates in a guard post at Yeoncheon, Gyeonggi Province. The shooting, where eight soldiers died, was also linked to bullying behavior by senior officers.

There are also claims that the tension with North Korea is taking its toll on the soldiers stationed near the heavily fortified Demilitarized Zone. Like many marine stations on the country's front-line islands, Ganghwa is within striking distance of North Korea. A year before, one of such islands was attacked, leading to the death of four people, including two marines.

Criticism
Actor, Im Hyeok-pil criticized many of the South Korean politicians who evaded their conscription service for taking roles in resolving the shooting incident.

Impact on policies
The authorities of the Republic of Korea Marine Corps announced to execute a 100-day program to promote the healthy and safe military culture within the military barracks. There is also plan to discharge marines who perpetuated acts of violence and to transfer them to other bases.

On January 13, 2012, the Republic of Korea Marine Corps General Military Court announced a ruling of the death penalty for Kim Minchan, and 20 years of imprisonment for Jung Joonhyeok, who had been arrested and indicted on suspicion of killing a higher officer.  They appealed immediately after the ruling, and according to Article 406 of the Military Court Act, defendants cannot abandon an appeal in connection with rulings of the death penalty, and life imprisonment, however, "it is only that it is not possible to abandon an appeal within a fixed period of time," not that an appeal is fulfilled automatically. 

On July 10, 2012, the Ministry of National Defense High Military Court maintained the original ruling from the first hearing for Kim Minchan, the perpetrator who was arrested and indicted on suspicion of killing a higher officer, and the appeal was dismissed.  However, the original ruling in connection with Jung Joonhyeok was overturned and was decreased to 10 years of imprisonment.  The second ruling was finalized by the Supreme Court on January 24, 2013.
