Two men have been charged with the murder of a woman whose body was found in bushland at Menai last year.
Homicide Squad detectives have been investigating the suspicious death of Najma Carroll, 33, whose body was found by a member of the public in bushland near Sandy Point Quarry off Heathcote Road, Menai, on July 29 last year.
Police later confirmed a burnt-out vehicle found in nearby bushland a week later was linked to the discovery of her body.
The vehicle was taken from the site for forensic examination.
Police confirmed a fire had been lit in the area where her body was found.
Ms Carroll had not been reported missing before the discovery of her body.
She was most recently known to reside in Sydney's inner west and was known to police.
The former student of selective Sydney Girls High School was on the 2004 Higher School Certificate distinguished achiever's list and had studied at Sydney University, but struggled with drug addiction since her teens.
A post on her Facebook page in October 2018 chillingly said: "Trust nobody".
Initial inquiries were conducted by Sutherland Shire Police Area Command, before detectives from the State Crime Command's Homicide Squad took over the investigation.
Police set up Strike Force Dalcassia to investigate.
Detectives were assisted by officers from the Central Metropolitan Region and NSW Crime Commission (NSWCC) during the investigation.
NSW Police said today that following extensive inquiries, detectives attended a correctional facility at Silverwater about 8.30am yesterday, April 6, and arrested a 57-year-old man.
He was charged with murder and remanded in custody.
About 8.30am today, investigators returned to the correctional facility and arrested a 43-year-old man, who was also charged with murder and remanded in custody.
Both men were due to appear at Sutherland Local Court via video link today.
Homicide Squad Commander, Detective Superintendent Danny Doherty, said the arrests were the result of tenacious work by detectives and support from members of the public.
"During the investigation, police identified that the last known sighting of Ms Carroll was when she left a hotel at Liverpool on Saturday, July 11, 2020, [at] about 7.30pm," he said.
"This was over two weeks before her body was discovered 15 kilometres away at Menai with horrific injuries.
"Following investigations, two men have now been charged over their alleged roles in the death of Ms Carroll, who was in the prime of her life."
Detective Superintendent Doherty said detectives were continuing to investigate the circumstances surrounding Ms Carroll's death.
Her mother thanked those who played a role in the arrests of the two men.
"I would like to thank the man that found Najma, the support from the Homicide Victims Support Group and the police investigating her death," she said.
"Najma was my beloved daughter who has a loving, generous and courageous spirit.
"Najma struggled with addiction from her teenage years, but she never resorted to crime to feed that addiction.
"We need to educate our sons and daughters that violence towards women is not acceptable and that culture needs to change.
"I thank everyone who has come forward and urge anyone with more information to contact police."
Police inquiries are continuing.
