The Crown has told a jury it must consider two key pieces of evidence when deciding the fate of the man accused of raping and murdering Christchurch schoolgirl Marie Davis.
Crown prosecutor Chris Lange began his closing address on Tuesday in the trial of Dean Cameron, 39, a roading worker, at the High Court in Christchurch.
Mr Lange says telecommunications records show the accused was near the 15-year-old's home about the time of her death, and near the Waimakariri River when her body was disposed of.
He also says DNA from blood and semen link Mr Cameron to the crime.
He says the accused also made "telling" revelations to associates during the days after Ms Davis' disappearance, including that if police had enough evidence, he would be in custody.
Mr Lange says there is no logical or reasonable way the jury could acquit Mr Cameron.
Mr Cameron denies raping and murdering Ms Davis.
