A young mother has pleaded guilty to murdering her four-month-old baby daughter in their Western Australian home.
Cassandra Rose Doohan was 18 when her daughter Anastasia Hand was found unresponsive by her partner, while he was in the shower for 15 minutes on May 2017.
The baby, who suffered catastrophic brain injuries, was taken to Bunbury Regional Hospital and transferred to Princess Margaret Hospital in Perth where she died two days later.
