On the Case with Paula Zahn (2009)

S4E4 A Tangled Past

Margaret Bradley, who struggled with Multiple Sclerosis, lived with her daughter Rhonda, a dedicated nurse. While Rhonda worked, a part-time aide assisted Margaret. However, in 2002, Margaret unexpectedly fell ill and passed away the following night due to alarmingly low blood sugar levels. Knowing her mother didn't have diabetes, Rhonda began to investigate the circumstances surrounding her mother's premature death, suspecting foul play. Her quest for the truth ultimately prompted law enforcement to launch a criminal investigation.
