Shane Jackson, 48, named in alleged Townsville murder-suicide

A Queensland man who is believed to have murdered a woman before killing himself has been pictured and named as police continue their probe.

A woman believed to have been murdered by her former partner had posted an anti-domestic violence message on her social media account.

The identity of the man believed to have killed Rebecca Walker, and then himself, in a north Queensland home has been revealed.

Police have confirmed they are not treating the death of a 48-year-old man, believed to be Shane Jackson, in Gulliver on Tuesday as suspicious.

Ms Walker was found dead alongside Mr Jackson at a Fulham Road property in the Townsville suburb of Gulliver.

Police said in a statement on Thursday that the death of the 45-year-old woman was suspicious, while the death of the 48-year-old man was being treated as non-suspicious.

Rebecca Walker posted an anti-domestic violence message on Facebook.

In May, Ms Walker posted on her Facebook account a message to coincide with domestic and family violence prevention month.

“Not Now, not ever. Together,” the campaign’s slogan read.

One friend posted on Ms Walker’s account: “Beautiful woman … (I’m) truly lost for words Bec RIP angel”.

Police also said in a statement on Thursday that “a formal identification of the pair and circumstances of their deaths is yet to be completed”.

“Police are working to understand the relationship between the pair, including any history of domestic violence.

“No further comment will be available on the matter until next week.”

No one else was injured, police said.
