The pair met when the widowed Ramadan knocked on Anderson’s door and asked for his help with some odd jobs around her home, including building flat-pack furniture.
Witnesses claimed to have heard multiple arguments between the pair in the days before Ramadan was killed.
On the morning of March 23, a taxi driver said he saw Ramadan and Anderson arguing about him arriving late to help her with some work.
About 3.30pm, a witness heard Anderson aggressively yelling at Ramadan, telling her “f*** you, fix it yourself”.
He left and arrived home “scary” angry, a woman living with him at the time said.
At 6pm, Anderson was back working at Ramadan’s.
There were signs of life until lunchtime on March 25, including a call from one of her phones to another and an electricity spike consistent with a hotplate, and then nothing.
The jury that convicted Anderson was the third he faced over the allegations.
One jury was discharged after being unable to reach a verdict and a second trial was discontinued before deliberations were reached.
In those hearings, jurors in the Victorian Supreme Court were told Anderson told his partner he was going to check on Ramadan about 9am on April 6, 2019 and to pick up some tools he had left at her house.
He said he found her body after going through the back door, which had been kicked open.
When police became suspicious about his involvement he confessed he had actually discovered her body between 1.30am and 2am on April 6 after he himself kicked in the back door.
Prosecutor Neil Hutton described the story as a sham and a charade.
The court heard Ramadan was known for wearing lots of jewellery, which was found alongside cash in her home after she was killed.
Supporters of Ramadan were in court for the verdict, including one who gave Anderson the middle finger after the guilty finding was read.
Anderson will face a pre-sentence hearing at a later date.
