The 19-year-old's body was recovered from Green Valley Creek in Canley Heights about 2pm on Saturday after a month-long search. Investigations are ongoing but her death is not believed to be suspicious. She was regularly smoking marijuana and told police during an arrest she used it to 'cope with stress'. Friends told Daily Mail Australia Ms Kasha had a strained relationship with her family in the months leading to her death and had alienated herself from loved ones as she became consumed by a new relationship. Just weeks before she vanished on April 28 - two days after her 19th birthday - Ms Kasha's mother was forced to take out an apprehended violence order against the teen. Merna Kasha was forbidden from going near her own mother after threatening to kill her during a heated argument She'd shown increasingly violent and paranoid tendencies culminating to an altercation between the two women on the morning of February 26. Ms Kasha woke about 8am and walked downstairs, telling her mother she was unable to breathe in her bedroom. The teenager had convinced herself her neighbours were 'releasing gas into her room which was vacuuming all the oxygen', court documents state. Despite repeated assurances from her mother that this was not the case, Ms Kasha became increasingly irate and eventually went to her neighbour's house. As she 'furiously knocked on her neighbour's door', Ms Kasha's desperate mother called the police. Ms Kasha returned home to find her mother on the phone to authorities and, according to documents, lost her temper. 'She said ''why did you call the police? I'm going to kill you'' and walked past the hallway toward the kitchen,' police facts state. A body believed to be that of 18-year-old Merna Kasha was found about 2pm on Saturday afternoon in the Green Valley Creek in Canley Heights - a month after she mysteriously disappeared Her mother was concerned she was going to grab a knife from the kitchen and tried to contain her in a bear hug, which prompted the altercation. Ms Kasha bit her mother and scratched her face. Her brother, who witnessed the altercation, again called police. She was arrested and charged with assault occasioning actual bodily harm, destroying property and stalking. An apprehended violence order was put in place to protect her mother - which she breached on several occasions before her disappearance. She was convicted over the matters and sentenced to a seven month community corrections order. One friend, who did not want to be named, said the 19-year-old 'felt like everyone was against her' and 'wasn't acting like herself'. Ms Kasha was convinced 'she didn't have anyone to talk to about her problems' and began smoking marijuana to cope. Merna Kasha, 18, disappeared on April 28 but police believe she communicated with family for several days after she was last seen On March 30 she was arrested with 1.5 grams of cannibas and a bong in her possession. She told police she'd 'smoked earlier in the day and would also smoke the bong again later', adding it 'helped with her stress'. Ms Kasha would often smoke marijuana in the staircase of a public car parking lot in Fairfield as she 'waited on her boyfriend to call or message her'. I have no idea why she would have been at the creek Merna Kasha's friend But she had never mentioned going down to Greek Valley Creek and friends say they can't imagine why she'd ever head there alone. By the time Ms Kasha disappeared on April 28, she'd either blocked or deleted most of her old friends. Her Instagram account was made private and she'd stopped replying to messages from people trying to check in on her. 'She was a really sweet hearted girl,' the friend said. 'My heart is just broken.' Police appealed for information into her mystery disappearance as recently as last Wednesday, which suggests new evidence came to light which prompted their discovery. Police at the scene on Saturday after receiving reports a body had been discovered The creek where Ms Kasha's decomposed body was found is just seven minutes from her family home. About 8pm on April 28 - the day of her disappearance - the teenager was dropped on a street just eight minutes from the creek. While she was never seen again, detectives believe she was in touch with family several times in the days after she vanished before contact stopped entirely. It's understood she was distressed about her mounting legal woes. The 18-year-old had no criminal history until March 2022, but in the six weeks prior to her disappearance she fronted up to court on seven occasions as her life spiralled out of control. Her matters last appeared in court on May 11, where she was convicted in absence for drug possession. Significant rainfall in recent weeks has helped to fill the creek, and police divers were required at the scene on Monday morning to aid in the investigation Ms Kasha was ordered not to be anywhere near her mother's home and told she must undertake drug and alcohol counselling as part of her community corrections order. Friends say she became increasingly private about her relationship with both her boyfriend and her family prior to disappearing. 'She really wanted to make things work. She never even told me his name,' one friend said of her boyfriend. The teenager's distressed parents were comforted by loved ones as detectives sifted through her belongings at the family home in Fairfield on Monday afternoon. 'They're devastated. Their baby is dead, how do you go on after that?' one family friend, who did not want to be named, said as she left the home. 'We're all mourning. What has happened with Merna is a tragedy.' Detectives wearing blue gloves and holding huge binders left her family home about 1.45pm as investigations into Ms Kasha's death continue.
