Charges have been filed against a Federal Way man in connection with the recent death of a 5-year-old girl.

Woo Jin Hahn, 29, the child’s father, was charged June 4 with five counts relating to domestic violence including second-degree assault of a child, two counts of third-degree assault of a child, fourth-degree assault and interfering with domestic violence reporting.

No charges have been filed yet related to the child’s actual death, but Hahn has made several statements that seem to take responsibility for it, according to charging documents.

Hahn’s child died on May 29, 2025, after he attacked her in their home in Glen Park Apartments in Federal Way. When police asked what he thought killed the child, for example, he replied, “probably the beatings from last night,” according to charging documents.

A spokesperson for the King County Prosecuting Attorney’s office said that the charges filed so far are the ones that prosecutors believe they can prove now, but that more charges could be filed based on what is found by the ongoing police investigation.

Hahn is currently in jail with a bail of $5 million. This bail amount was deemed necessary because “there is a likely danger that the defendant will commit a violent crime and will seek to intimidate witnesses and unlawfully interfere with the administration of justice,” according to charging documents.

At Hahn’s first court appearance, he was ordered to have no contact with his girlfriend, with whom he had been living at the time of his child’s death. Within two hours, he was attempting to violate the no contact order by contacting the girlfriend’s father and asking for her contact information, including her phone number. When the girlfriend’s father asked him why he was in jail, he was heard saying it was due to an issue with the child who died, according to charging documents.

In interviews with police described in the charging documents, the girlfriend described Hahn as “controlling” every aspect of her life and explained that she was scared of him.

This fear led the girlfriend to file a protection order for herself and her three children a year earlier, but she did not complete it. When asked why she did not complete the order, she stated that she was worried that Hahn’s child would end up homeless and living on the street, according to documents.

Child Protective Services (CPS) had also been referred to the family multiple times after signs of abuse were noticed on both Hahn’s daughter and the three other children in the home who are the girlfriend’s children. Charging documents state that the girlfriend told police that Hahn would threaten her and the children against reporting, and each time a CPS worker would contact the family, Hahn would “talk his way out of it.”

In April 2024, around the time she filed for the protection order, the girlfriend had also called 911 and reported an instance of domestic violence. She told police she ran to the front door and yelled for help after Hahn had struck her in the face, but Hahn had caught her and tackled her to the ground.

Hahn was initially charged for the attack, but the case was later dismissed after the girlfriend told a victim advocate that she did not want to participate in the prosecution.

Seven months later, the girlfriend told police she again tried to report the abuse, but ultimately did not. This time she took photographs of bruising on Hahn’s child and stated she was calling the police. She told police he then broke down the door of the room she was in and took the phone and the child in order to stop her. Police have reviewed these photographs and verified they were taken in November 2024.

Forensic interviews with the other three children in the home, along with records from the Division of Children, Youth and Families, continue to provide more details of the ongoing abuse suffered by everyone in the home.

By Hahn’s own admission, he would assault his child once or twice a week when he became “frustrated,” and that these “snapping points” would result in bruises that would last two to three days.

Hahn’s next court appearance is 9 a.m. June 17 for an arraignment where an initial plea will be entered. Defendants are innocent until proven guilty in court.
