1. Updates in the tragic mother-daughter murder case.

The car driven by murdered mother Karlie Pearce-Stevenson before her death — a red or maroon station wagon — has become a focal point of police investigations into the murder of Ms Pearce-Stevenson and her daughter Khandalyce.

ABC News reports that police have now searched properties in both Canberra and South Australia, and confirmed on Friday they were pursuing a “very strong line of inquiry.”

“Those premises belonged to people associated with Karlie and Khandalyce in some way,” South Australian Detective Superintendent Des Bray said. “I can’t go into the specifics of what those searches have been but I can say that those searches have been extremely productive.”

Police also they had talked to people about the case, including some who had been convicted of violent crimes and were currently behind bars.

Karlie’s remains were found in a NSW forest in 2010, while the remains of her daughter were found near a suitcase in South Australia earlier this year.

2. Sweden school attack being investigated for racist motive.

Video evidence seen by police suggests the masked man behind the double murder picked out his victims by their skin colour.

“He chose dark skinned people, not white. We are convinced it was a hate crime with a racist perspective,” chief of police in Trollhättan Niclas Hallgren told reporters, according to Guardian Australia.

“He was dressed in a way that suggested a racist background… video at the scene showed he acted in a military fashion.

“His actions and the way he looked draws the mind to the Nazis.”

A teacher and a student were killed in the tragic attack, and others were wounded by the swordsman.

3. Darren Hayes talks about his depression.

Darren Hayes, singer from Australian duo Savage Garden, has opened up about his depression in a candid Facebook post.

“One of the most challenging things about my depression is pretending I don’t have it. It’s exhausting,” the singer wrote in the lengthy 22 October message.

“The best way I can describe my depression is a poisonous dread. It’s a feeling in my stomach that registers the moment I wake up”.

He added in a follow-up comment: “I only share my experiences because I believe it’s important to remove the stigma that surrounds mental health. The wonderful aspect of this is, it’s possible to have a great life with resources and health options and to work out what works best for you.”

Hayes, originally from Brisbane, now lives in the United States with his husband Richard Cullen.

Parents have been left terrified by an anonymous note distributed in a small town in Minnesota, USA.
