A friend told today how he saw Marie Davis murder accused Dean Stewart Cameron disposing of a fishing knife, saying he did not want to be seen carrying it around.
Matthew Boyd told a depositions hearing in Christchurch District Court that Cameron buried the knife in the sand in the lake at Christchurch's Jellie Park.
He said he later led police to the knife.
Mr Boyd said Cameron told him that he did not want to be seen carrying the big knife around.
Cameron, a 38-year-old roading worker, is charged with the rape and murder of 15-year-old Marie Davis, whose body was found in the Waimakariri River about two weeks after her disappearance in April.
Mr Boyd told the court on the fifth day of the hearing that when he visited a woman in hospital, Cameron was there with flyers that had been distributed about the missing girl.
Mr Boyd and a member of Cameron's family have told of being unable to reach him by phone and cellphone on April 6, the day after Miss Davis was last seen.
Craig Matterson said he was at the Waimakariri River on April 6, moto-cross riding with his two sons.
On their way home, he saw a car coming up behind them fast on the shingle road and pulled over to let it past.
"I thought to myself, `Here's another village idiot on the river'."
It was a light dirty grey, or silver, Mitsubishi Gallant.
Tahlia Ono was at the riverbank with her family and saw a car speeding along the shingle. She said to her husband: "Why would you drive a car that fast on the shingle?"
She described the vehicle as a light coloured, grey or silver sedan.
Scientific evidence presented at the hearing today has been suppressed. The hearing is expected to end on Monday with evidence from the last of the crown's 33 witnesses.
The court is not sitting tomorrow, Christchurch's Show Day holiday.
