A 42-year-old San Dimas woman who allegedly set fire to her mother-in-law’s house and then drove away with the older woman’s remains was charged Friday with murder.

Un Young Lee appeared at Pomona Superior Court, but her arraignment on one count of murder was postponed until April 24, according to the Los Angeles County District Attorney’s Office.

Lee was taken into custody in Tustin Wednesday hours after firefighters battled an early morning fire at the victim’s home in Diamond Bar.

No one was found inside, but Los Angeles County Sheriff’s Department investigators had reason to believe the daughter-in-law of the woman who lived at the home had set the fire and fled with her body, authorities said at the time.

Lee was stopped in a SUV filled with plastic bags, and a detective on scene said he saw body parts inside as the vehicle was towed away for evidence.

The remains of 77-year-old Young Ja Lee were found inside the vehicle, a prosecutor said. She died at the home, according to an Orange County coroner’s office record.

The killing took place some time between Monday and Wednesday, the criminal complaint stated.

Un Young Lee was being held on $1 million bail. If convicted as charged, she could be sentenced to life in state prison.
