San Dimas woman is sentenced in death of mother-in-law

A San Dimas woman was sentenced Tuesday to nine years in state prison in the death of her mother-in-law, 77-year-old Young Ja Lee, last year, according to the Los Angeles County district attorney’s office. 

Un Young Lee, 44, pleaded guilty to one count of elder abuse and one count of arson of an inhabited dwelling and was immediately sentenced.

On March 25, 2015, firefighters put out a blaze at the Young Ja Lee's home in the 1200 block of North Diamond Bar Boulevard in Diamond Bar, prosecutors said. No one was found inside, said Lt. Eddie Hernandez with the Los Angeles County Sheriff’s Department. 

Later that day, authorities received a tip that Lee may have been killed at the home and that the woman who killed her was driving in the Tustin area. 

Police located Un Young Lee driving a minivan with Lee’s remains stuffed in four trash bags inside, Hernandez said.
