A four-year-old girl who died in a coma after being severely beaten by a middle school girl in her church died in a month.

According to the Incheon District Prosecutor's Office and family members, B (4), who was assaulted by a junior high student, A (16), at a church in Bupyung-gu, Incheon, died during a medical treatment at 2 pm the day before.

A (B) (4), who slept together in a nursery in the church at about 5:30 am on August 8, was arrested and immediately arrested by police at that time.

B was moved to a nearby general hospital by 119 paramedics at 11 am on the day of the report, but his head was injured and fell into a coma.

At the time of the incident, B's 9-year-old brother was sleeping together in the church nursery, but she had been away for a while to pray for early morning prayers.

A, who was about to go to high school this year, was reported to have slept with B's brother and sister by chance in this church, which was usually on the day of the incident.

The prosecution, which received the case from the police, accused A of Yang at the end of last month and charged him with arrest.

However, according to the death of B, the prosecution will examine the National Institute of Scientific Investigation for an autopsy and then change the name of the crime to injury by changing the duties.

A prosecution official said, "We will further determine whether there is a connection between the act of the defendant and the death of the victim and decide whether to change the place."

The first trial of A Yang will be held at the court of Incheon District 410 at 10:40 am on the 21st of this month.
