Daisy Mae Hayes, 74, was murdered in her Tierrasanta, San Diego home on December 14, 2011. Burney fled but later turned herself in after checking into a hospital.

Burney had a long history of mental illness, including a schizophrenia diagnosis and hospitalizations dating back to childhood. At trial the defense said she was in a psychotic, delusional state; the prosecution argued the killing was driven by anger and jealousy toward family. A jury found Burney sane at the time of the killing and convicted her of first-degree murder; she was sentenced to 50 years to life. The case centers on the clash between severe mental illness and criminal responsibility and devastated multiple family members.
