Los Angeles County District Attorney George Gascón announced July 29 that Weichien Huang has been charged with allegedly murdering her wife and attempting to murder her mother-in-law with a katana (sword) at their home in San Dimas on July 18.

“We are deeply saddened by this horrific violence and our hearts go out to the victims’ loved ones and community,” Gascón said. “This tragic case demonstrates the insidious problem of domestic violence that affects many throughout our country. Our Bureau of Victim Services is readily available to assist the surviving victim during this time.”

Huang, 44, is charged in case 24PSCF00461 with one count of murder and one count of attempted murder.

It is further alleged that the defendant inflicted serious bodily injury on a person 70 years or older and used a katana in the commission of the crimes.

Huang was scheduled to be arraigned July 29 in Dept. N of the Pomona Courthouse, but arraignment was postponed to July 30.

On July 18, Huang allegedly stabbed and killed her wife and injured her wife’s mother with a sword at their home in San Dimas. Victim Fei Chen Chen was pronounced dead at the scene. Victim Hsi H. was hospitalized with serious injuries. The defendant was hospitalized, then discharged and booked on July 24.

Prosecutors recommended bail be set at $3 million.

If convicted as charged, the defendant faces a maximum sentence of life in prison.

The case is being investigated by the Los Angeles County Sheriff’s Department.
