CHILLING footage has emerged of a former Australian student drinking a coffee laced with cyanide as she sat down to eat with friends in an up-market Indonesian cafe.

The CCTV images of Mirna Salihin consuming the drink that would kill her were shown on Monday evening on the ABC’s 7.30.

Also shown in the footage is Jessica Wongso, her friend who Indonesian police allege poisoned the iced coffee of her friend in a deliberate attempt to kill her.

Wongso, from Sydney, lived in Australia for seven years before going to Jakarta on holidays when she allegedly murdered Ms Salihin. The girls studied at the Billy Blue Design College in Sydney together.

Wongso has been on trial for the murder in a Jakarta Court. The footage shows the pair and another friend who also studied in Sydney, arriving at the cafe, greeting each other with a hug, before they glance at what food is in the cabinet.

They'd been friends for seven years but rarely got to see each other since Ms Salihin returned to Indonesia.

They then sit down at a table and Ms Salihin reaches for her drink and sips it. Prosecutors allege it had cyanide in it - and the results were almost instant.

She can be seen waving her hand in front of her face and moving her head from side to side, clearly in serious discomfort. She then slumps in her chair, her head lolling back behind her.

Cyanide has a corrosive effect and is a painful way to die, the 7.30 Report said.

Her new husband, Arief Soemarko, told the program he’d been told the drug "destroyed" everything in its path.

Mirna Salihin (pictured) was died after drinking laced coffee, it is claimed

"She's obviously in pain, several times she waves her hand at her mouth. I heard the drug destroys everything on the way... I heard her stomach was destroyed because [of] the poison. I’m devastated about how she felt that day."

Mr Soemarko said the friendship between his wife and Wongso was strained after Wongso didn’t like the relationship advice she’d been given.

Wongso is an Australian resident and many didn’t believe the murder trial would get underway.

But 7.30 reported Indonesian police and prosecutors were assisted by Australian Federal Police documents that showed Wongso suffers from mental health problems.

The information in the police file is now being used by Indonesian police.

Justice Minister Michael Keenan reportedly approved the handing-over of the AFP file that contained details of Wongso’s behaviour a year before she allegedly killed her friend.

The file contains confidential police intelligence reports that detail four suicide attempts that required hospitalisation, threatening behaviour towards colleagues and a major alcohol-fuelled road accident.

7.30, which has seen the file, also said it also contained information about an Apprehended Violence Order taken out against her by her ex-boyfriend.

Wongso’s lawyer, Yudi Wibowo, said the information was being misused.

"A report to the police in Australia has been treated as a crime by Indonesian police - that’s a misuse," he told 7.30.

"Yes, they are looking for death sentence, and my duty as a lawyer is to try to evade the death sentence and get her free, because there is not enough evidence," he added.
