Max Sica allegedly told a friend he wished he could take back what he had done, the Supreme Court in Brisbane heard yesterday.
Andrea Bowman was giving evidence about a conversation she had with Sica.
Sica, 42, has pleaded not guilty to murdering Neelma Singh, 24, Kunal Singh, 18, and Sidhi Singh, 12, at the Singhs’ home in Brisbane's north, on April 21, 2003. The three were children of former Fiji residents Vijay and Shirley Singh. The trial is in its night week.
The Courier Mail reports Bowman said that at one stage Sica asked her if she knew how hard it was to kill someone who said "Please don't. Don't, please."
Bowman said when she dropped him home Sica had asked if he "was busted" and said that if he was going to get "busted" he was glad it was from her.
She had first met Sica in 1987 when she worked in his family restaurant, but had declined his offer for a romance. They were in contact on and off.
She said she then sent Sica a sympathy card in 2003 when she saw media coverage of the murders and Sica’s images. He then called her.
"He talked straight away he was going to be a suspect or he was a suspect and police were sure he had done it," she said.
She said she went to see Sica and kept in contact.
Bowman said in February 2008 she had a conversation in a park with Sica about scenarios that could have led to the Singhs' death.
Then in March, Sica rang and sounded "down" and said he had been drinking.
Bowman said she drove over and picked him up and they drove to a park.
They had a conversation for about four hours in which she said she didn't believe the murders were in cold blood.
They went over various scenarios about what went on and one stage Sica allegedly said: “Maybe I killed Kunal in the bathroom, maybe I killed him in the bedroom.”
She said they spoke about the weapon and Sica said it was like a spade but wasn't a spade.
She asked if he had any remorse .
Sica had said: "If I could take back what happened I would ... I have remorse," she told the court.
She told the court Sica had then said: "Do you know hard it is to kill somone when they say please don't, don't please."
The trial also heard Neelma Singh using the name Naughty Nimmy in a computer chat with Max Sica, using the name "Pam Dickles" in which they discussed threatening her father.
Peter James Moore, then a police information technology expert, told the court he had found the stored chat on Neelma's computer.
He also found hacking software and naked photographs of Neelma taken from Sica’s computer at one of his homes.
He told the court he found 'cyber scrub' on the computer at his second home. This deleted files beyond recovery.
