News in 5: Vegas killer's partner arrives in US; Faulty pregnancy tests removed from shelves; HSC cheats caught.

1. “We have a lot of questions”: Vegas killer’s Australian girlfriend arrives in US.

Former Bachelor Matty J has become an uncle (again!).

His sister, Kate, has given birth to a baby girl called Millie, her second child after son George who is 17 months old.

Matty J told Be Kate is still in hospital after giving birth on Monday but “she’ll be out soon”.

Matty J and his girlfriend Laura Byrne began dating after last season’s The Bachelor.

From all accounts, things are going well – judging by the introduction to his “nearest and dearest” photographed above.

5. Journalist Kim Wall ‘stabbed 15 times’ onboard submarine, and videos of decapitation found on accused’s computer.

A Danish inventor charged with murdering Swedish journalist Kim Wall in his home-made submarine had video footage on his computer showing women being violently killed, a court has heard.

A police prosecutor on Tuesday said officers found images “presumed to be real” of women being strangled and decapitated on the hard drive of Peter Madsen’s computer in a laboratory he ran.

That, together with new post-mortem evidence showing Wall was stabbed 15 times in the abdomen and genitals, as The Guardian reports, the case is building against Madsen.

Madsen denies murdering Wall, telling police the computer was not his and that Wall died accidentally when she hit her head on a heavy hatch cover inside the submarine.

The 30-year-old freelance journalist went missing while covering a story on Madsen and his home-made submarine. On August 23, police identified a headless female torso washed ashore in Copenhagen as Hall’s.

6. Students caught cheating in HSC exams.

Some Victorian students sitting their final high school exams have been caught texting friends for answers and copying multiple choice questions, an education authority has found.

Up to 68 students cheated in their exams, including one found texting another student, while five others copied multiple choice answers off another teenager, a Victorian Curriculum and Assessment Authority report released on Wednesday showed.

The students were nabbed in 2016 and several received penalties for the breaches, which included a reduction of final grades or having their exam mark lowered.

It serves as a reminder to students around the country embarking on their final exams this week.

7. US Panel consensus that Russia meddled in the election.

The head of the US Senate Intelligence Committee said on Wednesday there was a general consensus in the panel that Russia interfered in the 2016 US presidential election.

Evidence on the issue of the collusion between Moscow and the Trump campaign is still being examined, Republican Senator Richard Burr told reporters on Wednesday.

"The issue of collusion is still open... We continue to investigate both intelligence and witnesses," Burr said.

The committee had interviewed "everybody who had a hand" in an intelligence assessment, which concluded Russia meddled in the election, he said.

"I think there is a general consensus among members and staff we trust the conclusions," Burr told reporters.
