Merna Kasha was banned from going near her own mother after threatening to kill her during a heated argument.
The 19-year-old’s body was found around 2 p.m. Saturday in Green Valley Creek in Canley Heights after a month-long search.
The investigation is still ongoing, but her death is not considered suspicious.
She regularly smoked marijuana and told police during an arrest that she was using it to “cope with stress.”
Friends told Daily Mail Australia that Ms Kasha had a strained relationship with her family in the months leading up to her death and that she had become estranged from her loved ones as she became consumed with a new relationship.
Just weeks before she disappeared on April 28 – two days after her 19th birthday – Ms Kasha’s mother was forced to issue a warrant for the teen’s arrest.
Merna Kasha was banned from being near her own mother after threatening to kill her during heated argument
She had displayed increasingly violent and paranoid tendencies that culminated in an altercation between the two women on the morning of February 26.
Mrs. Kasha woke up around 8am and walked downstairs and told her mother that she couldn’t breathe in her bedroom.
The teen convinced herself that her neighbors were “leaking gas into her room, sucking up all the oxygen,” court documents say.
Despite repeated assurances from her mother that this was not the case, Ms. Kasha grew increasingly furious and eventually went to her neighbor’s house.
While she “knocked furiously on her neighbor’s door,” Ms. Kasha’s desperate mother called the police.
Ms Kasha returned home to find her mother on the phone with authorities and, according to documents, lost her temper.
She said ‘why did you call the police? I’m going to kill you” and walked down the hall to the kitchen,” police said.
A body believed to be that of 18-year-old Merna Kasha was found around 2 p.m. Saturday afternoon in Canley Heights’ Green Valley Creek — a month after she mysteriously disappeared.
Her mother feared she would grab a knife from the kitchen and tried to hold her in a bear hug, sparking the altercation.
Mrs. Kasha bit her mother and scratched her face. Her brother, who witnessed the altercation, called the police again.
She was arrested and charged with assault involving actual bodily harm, destruction of property and stalking.
An arrest warrant for violence was issued to protect her mother – whom she violated several times before her disappearance.
She was convicted of the cases and sentenced to a seven-month correction from the community.
A friend, who declined to be named, said the 19-year-old “felt like everyone was against her” and “wasn’t acting like herself.”
Ms. Kasha was convinced that “she had no one to talk to about her problems” and started 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 water pipe in her possession. She told police she had “smoked earlier in the day and would also smoke the hookah later,” adding that it “helped with her stress.”
Ms. Kasha often smoked marijuana on the steps of a public parking lot in Fairfield while “waiting for her boyfriend to call or message her.”
I have no idea why she would have been at the creek
But she never said she went to Greek Valley Creek and friends say they can’t imagine why she would ever go there alone.
By the time Ms. Kasha disappeared on April 28, she had blocked or deleted most of her old friends. Her Instagram account was made private and she stopped responding to messages from people trying to check in.
“She was a very sweet girl,” said the friend. “My heart is just broken.”
Police last Wednesday called on information about her mysterious disappearance, suggesting new evidence has come to light that led to their discovery.
Police on the scene on Saturday after receiving reports that a body had been found
The creek where Ms. Kasha’s decomposed body was found is just seven minutes from her childhood home.
On April 28, the day of her disappearance, around 8 p.m., the teen was dropped on a street just eight minutes from the creek.
Though she was never seen again, detectives believe she had contact with family several times in the days following her disappearance before losing contact altogether.
It is clear that she was saddened by her mounting legal problems.
The 18-year-old had no criminal record until March 2022, but in the six weeks leading up to her disappearance, she faced court seven times when her life spiraled out of control.
Her cases last appeared in court on May 11, where she was convicted in absentia for drug possession.
Significant rainfall in recent weeks has helped fill the creek, and police divers had to arrive at the scene Monday morning to assist with the investigation
Ms. Kasha was ordered not to be anywhere near her mother’s house and was told to undergo drug and alcohol counseling as part of her correction order.
Friends say she became increasingly private about her relationship with both her boyfriend and her family before she disappeared.
“She really wanted to make things work. She never even told me his name,” a friend said of her boyfriend.
The teen’s ailing parents were comforted by loved ones when detectives searched her belongings at the family home in Fairfield Monday afternoon.
“They are devastated. Their baby is dead, how are you after that?’ said a family friend, who did not want to be called by name, as she left the house.
“We are all grieving. What happened to Merna is a tragedy.”
Detectives wearing blue gloves and holding huge binders left her family home at around 1:45 p.m. as the investigation into Ms. Kasha’s death continues. Several brown paper bags of evidence were removed from the scene
