Police spoke to almost 200 people on the north bank of the Waimakariri River yesterday as the investigation into the death of Christchurch teenager Marie Davis continues.
Detective Senior Sergeant Virginia Le Bas said police and members of the Kaiapoi Community Watch Group questioned people in the areato help build a better picture of what occurred on the night the 15-year-old went missing.
Marie's body was found in the river on Thursday - nearly two weeks after she disappeared from her Papanui home on April 5.
"The public have been extremely helpful but there are people who have been seen in this area on Sunday, April 6, who have not yet come forward and are yet to be identified," Ms Le Bas said.
She was particularly interested in speaking to people who use the motorcycle area on the north bank of the river.
Police also distributed flyers to help jog the memories of people who may have seen Marie before she went missing.
Ms Le Bas said there was someone in the community who knew what happened to Marie, and she appealed for anyone with information about her disappearance to come forward.
Asked about suspects, she said: "There are people who are more interesting than others to us."
Marie's body will be released to her family today.
