A San Dimas woman was sentenced to nine years in state prison on Tuesday after pleading guilty to elder abuse in connection with the death of her mother-in-law, according to the Los Angeles County District Attorney’s office.

Un Young Lee, 44, pleaded guilty to one count of elder abuse causing death and one count of arson of inhabited dwelling.

Firefighters responded to reports of a fire at the mother-in-law’s home in the 1200 block of North Diamond Bar Boulevard in March 2015.

No one was found inside the home, but Lee was found driving her SUV in Orange County later that day, officials said.

The SUV filled with plastic bags, and a detective on scene said he saw body parts inside as the vehicle was towed away for evidence. Authorities later discovered the remains of the 77-year-old victim, Young Ja Lee, inside the car.

Prosecutors believe the elder Lee died sometime between March 23 and March 25. The younger Lee was immediately sentenced after pleading guilty.
