A workmate of Liam James Reid has told the High Court at Christchurch of the murder accused mentioning strangulation during sex.
The workmate at an industrial refrigeration plant, Warren James Wallace, said Reid mentioned sexual matters in passing on a couple of occasions, Christchurch Court News website reported.
He referred to "past girlfriends, possibly" and spoke of "strangulation with the hands around the throat".
The witness told the court: "I said something like, `That's pretty out of it'."
Cross-examined by defence counsel David Bunce, he was asked if Reid had been talking about "unusual but consensual activity during sex".
Mr Wallace replied: "There was no mention of consent. I don't know."
Mr Bunce: "He didn't explain to you that this was supposed to enhance sensation during sex?"
Mr Wallace: "I don't recall."
A friend of Reid's former girlfriend - the girlfriend has name suppression - told the court she learnt on the morning of November 15, 2007, that Reid and the girlfriend had split up.
She told the court that the girlfriend had been supplying her with cannabis tinnies about once a week.
November 15 was the day that Christchurch woman Emma Agnew disappeared, and her body was found 11 days later at Spencer Park.
Reid denies charges of raping and murdering Miss Agnew, and raping, sexually violating, robbing, and attempting to murder another woman in an attack in Dunedin nine days later.
The defence says he was not involved in either crime.
Earlier the court was told that Reid's fingerprints were found on the window and rear passenger door of the car belonging to Miss Agnew.
The evidence was given by Detective Constable Craig Johnson on the third day of 36-year-old Reid's trial before Justice Lester Chisholm and a jury.
Questioned by crown prosecutor Brent Stanaway, Mr Johnson said fingerprint "lifts" had been taken on November 16 and 17, the two days after the car had been found.
The accused's prints were found on the window and the door of the rear passenger door, and a pubic-like hair, identified by DNA testing as being highly consistent with coming from the accused, had been found in the car.
He said Luminol testing had been carried out but no areas in the car showed positive for blood.
The defence questioned Mr Johnson closely about the measures taken to protect the evidence associated with the car, and ensure it was not contaminated.
A man walking his dogs told the court how he checked an area a few metres from a Spencer Park walking track when the dogs showed an interest two days in a row - and found the body of Miss Agnew lying beneath foliage.
Stuart Monk said the area was not visible at all from the track. He had to fight through some bush and then crawl under a fallen tree.
He then saw a mound of foliage that did not look right. "The rest of the forest floor was pretty flat, but this looked like a man-made construction."
The body was completely covered, but he moved some foliage with his foot and saw the ear and head of a female body.
"I knew there was a young lady missing and I thought it was probably her," he said.
