Woman, 65, sentenced to 25-years in prison for murdering 90-year-old mother

A 65-year-old woman who police say admitted to killing her 90-year-old mother during a visit to Warminster from South Korea will serve 25 years in prison following a plea agreement.

Authorities say Sun Hee Kim murdered her mother, Chung Sook Chang, in an apartment of Potter Street in Warminster on April 28th, 2018. An investigation concluded that Kim attacked Chang from behind and stabbed her in the head, neck and face with a shards of a broken picture frame and a plate.

According to police, Kim called 911 after the attack and told the dispatcher "I killed a woman, I killed my mother."

Witnesses reported hearing slapping, crying and yelling in a foreign language in the moments shortly before the attack.

Kim, police say, was visiting her mother from her native South Korea and was scheduled to fly home the day after the attack.

Medical records obtained by investigators from doctors in South Korea indicate that Kim has suffered from bipolar disorder and schizophrenia for 40 years, but she had recently refused to continue treatment options.

Kim will be deported upon her parole from Pennsylvania State Prison, police say.
