An appellate court on Thursday upheld a prison term for a hunter who shot and killed a taxi driver, mistaking the victim for a boar.

The 73-year-old professional hunter was sentenced to one year and four months in prison for murder by occupational negligence at an appellate trial in the second criminal appellate division of Seoul Western District Court on Thursday, reducing the sentence by four months from the lower court’s ruling.

The shooting took place around 8 p.m. on April 29 during a night search of a boar under the admission of the local police authority at Bukhansan in Eunpyeong-gu, northwestern Seoul.

With low visibility due to the darkness, the officer mistook the victim urinating off the road as a boar, he said in a police investigation.

The victim in his 70s was shot in his right arm and stomach. The rescue personnel arrived at the spot soon after the officer’s report and moved the victim to a hospital, but the victim died around five hours after being shot.

The appellate court said that the hunter failed to fulfill the duty of care required in his work, saying, “The location (of the incident) was adjacent to the road where cars frequently move, having a subsequent possibility of pedestrian appearance even during the nighttime.”

The court added that since the defendant is an experienced hunter, he should’ve done due diligence. The bereaved family wanted to see him punished, it added.

The defendant paid 50 million won ($40,580) as a deposit for a criminal agreement, which was considered as a mitigating factor, according to the ruling.
