A 12 person jury is set to hear from the first key witnesses in a murder trial in Launceston's Supreme Court.
On Wednesday, the jury heard opening remarks from Crown Prosecutor John Ransom - who outlined the evidence, the opposition's plans and what they propose happened.
48 year old Natalie Maher has plead not guilty to murdering her mother 71 year old Veronica Corstophine - whos body was found in late October 2019 at her Keane St, Launceston home.
The proesecution allege Ms Corstophine died some time between October 3, 2019 at 2pm and October 5 2019 when Ms Maher flew to Western Australia - most likely before 10pm on October 3.
It's alleged a pillow was used to suffocate Ms Costorphine.
Defence lawyer Evan Hughes urged the jury to consider all the evidence and all the possibilities - including that someone else could have killed Ms Corstophine - the evidence against Ms Maher all circumstantial.
The jury is set to begin hearing from key witnesses today - including police and family.
