A man has been charged with the murder of a mother of three who was found dead at her home on Victoria’s Phillip Island last week.

A 41-year-old man from Paynesville, in the state’s east, was arrested this morning and interviewed by police, before being charged with murder.

He will appear at Bairnsdale Magistrates’ Court today.

Samantha Fraser was found dead in the garage of her Cowes home on July 23.

Homicide squad detectives said last week she had been assaulted in the hours before she died.

Anyone on the island or in the nearby town of San Remo that has CCTV footage from the day Ms Fraser was found dead, has been asked to contact police.

Police have also asked anyone who saw a hooded man near Mr Fraser’s Seagrove Way home on the day she died to come forward.

The man’s hoodie was described as being black with “a distinctive dark blue band on the midriff and arms”.

Ms Fraser, 38, was a psychologist who worked at the Cowes Medical Centre.

On the day of her death, she met with friends in the morning but failed to show up to a midday appointment.

Officers conducting a welfare check discovered her body, after she failed to pick up her children from the local primary school that afternoon.
