Alarming new footage and evidence has emerged in the Karen Ristevski murder mystery.
The Herald Sun reports that police have seized an iPad from the Melbourne home of the murdered mother containing strange searched including how police detect blood, trace phones and how to delete mobile phone data.
The shock news comes as a Channel Nine news crew spotted Vasko Ristevski - the brother of Ms Ristevski's husband, Borce - lurking near the area where her body was found wedged between logs at Mount Macedon, near Melbourne.
The crew were in the deserted location to film a story about the progress of the case when they spotted Vasko heading back towards his truck.
Journalist Martin King asked: 'Can you tell us what you're doing here?'
Earlier this week Victoria police released security images of a black vehicle believed to be Karen's Mercedes-Benz SLK coupe.
The car was seen in Diggers Rest at 11.12am June 29 2016, the day she disappeared.
According to the Herald Sun, police believe Karen's husband Borce Ristevski could be driving the car captured in the CCTV images, with Karen's body in the vehicle.
Ristevski has been a known murder suspect in the case after Karen's body was found on February 20.
