In 2018 she was arrested in Baltimore in connection with the death of her deaf and partially blind sister, Wendy Blackstone, which took place in March 2015. Blackstone allegedly drugged her sister, placed her in the garage with her three dogs and set it on fire. Her sister was found in the garage of a Studio City, California, home with a suicide note in her hand. The newspaper reported the note was written by Blackstone as her sister was legally blind and needed hearing aids. Los Angeles Police Department detectives allege Blackstone was likely frustrated with her sister's long-term care. Blackstone is facing a murder charge as well as three counts of animal cruelty after Los Angeles County prosecutors filed the charges in March. Blackstone was arrested in 2015 after her sister died but she was released without any charges. The district attorney's office ordered an investigation into the death just days later.
