A lawyer knew her husband was connected to criminal activity and tried to destroy evidence linking him to a murder because she couldn't live without him, a jury has heard.
As Ali Cevik was sitting in a police cell in the early hours of May 28, 2019, his wife Alev Rojda Oncu desperately tried to find out what had happened.
"I can't do life without you," she texted after his arrest.

Crown prosecutors allege this was what spurred the 32-year-old Sydney solicitor to try deleting CCTV footage around her Blacktown home which showed Cevik leaving with another man before the murder was committed.
"She did that in order to obstruct or interfere or pervert the course of justice that was in train because (Cevik had) been charged with an offence," crown prosecutor Philip Hogan told jurors on Thursday.

"She did it, the Crown says, so that she wouldn't have to do life without him."
Cevik pleaded guilty to the murder, details of which cannot be published under court order.
Oncu had been in a relationship with Cevik for six to eight years and first met her husband when he was a "disciplined, hard-trained" mixed martial arts fighter.
However, he then became involved in drugs and people with a "bad reputation," Hogan told Parramatta District Court during a closing address.
The couple got married, bought a home, lived in the granny flat and rented out the main house.
"Life's looking good except that Ali Cevik had gone off the rails but … she can't do life without him," Hogan said.
Hours before the murder, a phone call with Cevik would have made the solicitor aware her husband was about to become involved in serious criminal activity.
"I don't know if I come home tonight. The things I'm about to do, it's not going to be OK," he said.
The following day after police visited her house, Oncu allegedly unsuccessfully tried to unplug the CCTV system located in their bedroom before asking technician Salar Norouzi to attend her home.
"She told him that she wanted to erase the footage," Mr Hogan said.
When police reviewed the CCTV hard drive, they found everything from before when Norouzi was there had disappeared.

In August 2022, police were able to retrieve the missing footage using updated software.
The missing footage showed Cevik leaving prior to the murder plus Oncu, after her husband's arrest, going underneath the main house with a laundry basket and then meeting with a man and a woman who took a black bag to dispose of in the park behind the home.
Earlier on Thursday, Oncu gave evidence from the witness box saying she had no reason to think anything in her Blacktown home would have been relevant to police.
She denied asking anyone to delete the footage, saying she had worked hard to get where she was in the legal profession.

"I would never do anything to obstruct or to mislead the system in general. I would never do anything of that nature," she told the court.
The four men involved in the murder, including Cevik, either pleaded guilty or were found by a jury to be guilty. A fifth man pleaded guilty to being an accessory.
The trial with Judge Mark Buscombe continues.
