The murder of mother of three Monika Chetty remains unsolved after she was doused in acid and left to die in December of 2013.
Monika hid in the woods for 10 days following the attack before being found by a resident who heard her cries. She had suffered burns to 80 percent of her body, and died in Concord Hospital, Sydney, 28 days later.
Speaking at a press conference alongside Monika's son and ex-husband, Det. Chief Insp. Dean Johnstone said: "In nearly two decades as a detective I have never seen injuries of this nature...I urge anyone with any information to come forward so justice can be served to Monika and her family"
Police believe the 39-year-old nurse knew her attacker but was afraid to reveal his identity. When questioned, Monika said an unknown man had thrown acid on her after she refused to give him a cigarette, but officers have determined her story was a lie.
It is now understood that Monika may have been involved in a marriage scam, which police believe might be connected to the attack.
