Kerryn's brother, Matt Tate, described the identification of a suspect as uplifting and urged anyone with information about Fisher to come forward.

Investigative genetic genealogy played a crucial role in identifying Fisher as a suspect by using DNA from the crime scene uploaded to a public database.

Fisher served in the Australian Army and was a carpenter by trade, with his life and movements now under scrutiny as part of the investigation.

Kerryn Tate, a mother of twin girls, was found dead the day after she was last seen, with severe injuries indicating a violent attack.

DNA evidence collected from the crime scene has linked the late Terrence Fisher, who died in 2000, to Tate's murder after 45 years.

Fisher was known to have lived in the Rivervale and Manning areas and was active in the Fremantle Sailing Club around the time of Tate's murder.

To encourage public tips regarding Fisher's activities during the time of Tate's murder, police have established a roadside facility in Karragullen.

West Australian police have made a significant breakthrough in the cold case murder of Kerryn Tate, who was last seen alive on December 29, 1979.

Kerryn's sister, Annemarie Tate, expressed relief at the identification of a suspect, stating that knowing Fisher is deceased provides peace of mind.

Fisher is also considered a potential suspect in the murders of two other women, Barbara Anne Western in 1986 and Kerry Suzanne Turner in 1991.

Acting Assistant Commissioner Paul Coombes emphasized WA Police's commitment to solving cold cases and expressed hope for providing closure to the Tate family.

Detective Acting Senior Sergeant Dion Selby highlighted the importance of public assistance in building a clearer picture of Fisher's movements and urged anyone with relevant information to reach out to police.
