Australian woman Erin Patterson has been charged with three counts of murder and five counts of attempted murder.  

Her former in-laws Gail and Don Patterson as well as Gail's sister Heather died from suspected toxic mushroom poisoning in July, after eating lunch Erin Patterson allegedly made.  

Gail's husband Ian was hospitalised.  

Three other charges relate to incidents in 2021 and 2022, when police allege that a 48-year-old man became ill after meals.  

Australian correspondent Murray Olds told Mike Hosking that Police searched her property with specially trained forensic sniffer dogs.  

He says those dogs are trained to look for things like USBs and SIM cards.
