Man accused of killing, dismembering mother in Waikiki apartment pleads guilty to manslaughter

News

A man accused of killing his mother two years ago in their Waikiki apartment has pleaded guilty.

Yu Wei Gong was originally charged with second-degree murder.

Gong was arrested on April 11, 2017. According to a police complaint at the time, he confessed to 911 dispatchers and stated, “I killed my mom.”

Last week, prosecutors added charges of abuse of a corpse and identity theft. “The allegation was he paid rent with the mom’s checking account,” explained prosecutor Wayne Tashima.

On Friday, Sept. 28, he pleaded guilty to manslaughter, abuse of a corpse, and identity theft, working out a deal with prosecutors that eliminates the potential of staying locked up for life.

With a Mandarin-language interpreter at his side, he answered a questions from Judge Paul Wong.

The 27-year-old said he was prescribed medication, but did not take any Friday. He told the judge he understood the extent of what he is facing.

According to court documents, Gong admitted to killing his mother, Liu Yun Gong, back in September 2016 at their residence on Launiu Street. He told the woman’s coworker that she was in China, then later said she was on a neighbor island and had left her phone at home.

Gong said it was an accident, and the two had gotten into an argument because he did not want to go to school and instead get a job.

When officers asked where his mother was after searching the unit, Gong uttered she was “in the fridge,” according to the complaint. An officer then checked the freezer and found human remains, including two arms with hands and a decapitated head, in numerous plastic trash bags.

The remains were positively identified as Gong’s mother, and the medical examiner’s office determined the cause of death was injuries sustained from blunt force trauma to the head. The manner of death was ruled a homicide.

Gong and his public defender worked out a deal with prosecutors, admitting he killed his mother while “under the influence of extreme mental and emotional disturbance.”

“The specifics of the agreement, I can’t disclose that. I can tell you the family was consulted,” said Tashima. “Everybody is satisfied with the result.”

Gong faces 20 years for manslaughter, and one year for abuse of a corpse, which would be served concurrently.

He also faces an additional 10 years for identity theft, which would be served separately.

Gong is currently being held at Oahu Community Correctional Center, and will be sentenced in January.
