We’ve rounded up all the latest stories from Australia and around the world – so you don’t have to go searching.

1. Police believe a man shot in self-defence may have been a serial killer.

A woman in West Virginia who shot a man in self-defence may have taken down a serial killer.

The woman realised something was wrong after Neal Falls arrived at her apartment after answering an ad she’d placed for an escort service on Backpage.com.

The woman told KPTV that she knew the man was there to kill her. “I could tell that he had already done something because he said that he was going to prison for a long time.” she said. “And that’s when I knew he was going to kill me.”

After a struggle, the woman grabbed Falls’ gun and shot him. When police arrived, they found a “kill kit” in the man’s Subaru. A list of names, believed to be of future targets, was found in Falls’ pocket.

He is now being investigated in relation to other violent, unsolved murders. The woman has been treated for a broken vertebrae and lacerations, but has since been released from hospital.

2. Bronwyn Bishop claimed trip to colleague’s wedding as a “business expense”.

Embattled Speaker Bronwyn Bishop remains in hot water after it was revealed she claimed a trip to attend former frontbencher Sophie Mirabella’s Albury wedding in 2006 as a business expense.

“She was on official business, as the chair of the family and human services committee,” a spokesman for Mrs Bishop said.

Whilst the committee was conducting an inquiry into work and family balance at the time of Mirabella’s wedding, the ABC reports no public hearings were held in Albury.

The news comes after revelations that she chartered a helicopter from Melbourne to Geelong to attend a Liberal party function, which led to Prime Minister Tony Abbott placing the Speaker on probation.

Federal Opposition spokesman Pat Conroy said that Bishop should repay the money, asking “Is there anything Bronwyn Bishop actually pays for herself – without being forced to, of course?”

3. Amy Schumer says her “heart is broken” over shooting during Trainwreck screening.

The victims were Mayci Breaux, 21, and 33-year-old Jillian Johnson. Nine others were injured in the attack.

The shooter, who also died at the scene, has since been identified as 59-year-old John Russell Houser.

Schumer has since responded to the shooting, writing on Twitter that her “heart is broken”.

My heart is broken and all my thoughts and prayers are with everyone in Louisiana.

4. Social media rallies around mum stuck in hospital with a sick newborn.

When Kaylee Goeman took her six-week-old son to the Royal Victoria Hospital in Canada she was unable to afford the hospital’s parking fee, so paid for a parking meter for four hours.

When it became clear she would be at the hospital for much longer, she turned to a local mother’s group on Facebook for help.

“I’m at RVH with my newborn and we now need to do more ultrasound and xrays.” she wrote.

“I put all my change in the street meter but it’s going to run out at 3.30. Will I get towed or just a ticket? I can’t leave my newborn to run out, and we didn’t expect it to be this long.”

Other mums in the area quickly rallied around Goeman and fed the meter for her so she would avoid getting a ticket.

Goeman told Today she was overhwelmed by the community’s support.

“Knowing I had all these ladies there for me, to help me with parking, meals, and even hugs made me able to focus just on my son and his needs,” she said.
