Accused drug mule Cassandra Sainsbury will struggle to get a fair trial in Colombia after being publicly ridiculed by her fellow Australians, an expert has warned.

Ms Sainsbury, 22, was arrested on April 11 at El Dorado International Airport in Bogota with 5.8 kilograms of cocaine in her luggage.

She claims to have been framed, but a number of Australians were quick to rubbish her defence with comments alleging Ms Sainsbury’s guilt on her crowdfunding page.

University of Newcastle international law professor Dr Amy Maguire said the public’s jump to conclusions could negatively impact her trial.

“In terms of the social media age there is a problem of the impact of what’s published online prior to trial,” Dr Maguire told The New Daily.

“The thing that strikes me and the public discourse around these types of cases in Australia is that a lot of people who comment seem quite comfortable with the idea that if you find yourself overseas with drugs then there’s no one to blame but you, whatever the outcome could be.”

The warning comes as new photos were released Tuesday showing Ms Sainsbury handcuffed in Colombia, standing with 18 packages said to contain cocaine.

Dr Maguire urged people to think twice before commenting to ensure the kind of “lawful, fair trail” they would want in the same predicament.

“If nothing else, if people could imagine themselves or a loved one in this sort of circumstance before they post, query if this is how they would want their loved one to be treated,” she said.

“Being honest, the vast majority of people would have to say no, if that was my daughter or my sister, I’d want her to be treated fairly.”

The online FundRazr campaign set up to help Ms Sainsbury fight her charges failed to reach its target of $15,000 on Tuesday.

Just over 100 people pledged to donate $4,232 to the FundRazr account, but dozens of Australians have questioned Ms Sainsbury’s innocence.

“I can’t believe people are actually contributing to this! She is so clearly guilty. I mean come on, who goes to Colombia for a working holiday? lol,” one commenter wrote.

“No one from South Australia is that naive, not with the drug culture there! Let her hang,” another said.

“If it walks like a duck and quacks like a duck … it’s a girl deliberately trafficking coke to help fund her wedding,” wrote a third.

Cassie’s mother, Lisa Evans, said her daughter had been duped into bulk-buying boxed headphones containing concealed drugs from an acquaintance.

She said Ms Sainsbury had purchased the headphones as presents for her bridal party and friends for her upcoming wedding.

Ms Evans told Channel Nine’s Today show she didn’t know how someone could use her daughter to traffic drugs.

“Cassie is just, ‘I didn’t do it mum, you have got to get me out’ and crying hysterically,” Ms Evans said.

“She is just so scared that she is caught up on the other side of the world for something she didn’t do with no support over there, no nothing.”

Ms Sainsbury is facing up to 25 years in jail and is currently being held in the notorious ‘El Buen Pastor’ (The Good Shepherd) women’s prison, which is reportedly overpopulated by as many as 50,000 inmates.
