Murdered Tokai teen's phone has allegedly been found
Earlier, police confirmed three people were being questioned in connection with the murder.
CAPE TOWN - Eyewitness News has learnt police have apparently found the mobile phone of 16-year-old Franziska Blöchliger, who was murdered in Tokai Forest.
Earlier today, police confirmed three people were being questioned in connection with the murder.
The Constantia Waldorf School's Thomas Knemeyer is close to the family.
"Police have found the phone and they are examining it, I suppose, for information or maybe finger prints. That is interesting in connection with the fact that three young men in their early 20s have been arrested. I don't know this [for sure] but my guess is that one of the three had the phone."
The three who were arrested are yet to be charged.
Police have emphasised they can't divulge further details.
The reward being offered for information that could help convict Franziska's killer has been doubled.
The cause of death is still unknown but police suspect that she was strangled.
Knemeyer says the reward for information is now more enticing.
"They have doubled the reward from R50,000 to R100,000 and there have been two other people who have offered to contribute to this reward."
The Blochliger family has also roped in forensic investigator David Klatzow.
WATCH: Thousands gather to mourn Franziska Blöchliger
Last night, hundreds of people held at a silent vigil in Tokai Forest in memory of Blöchliger.
She went missing after she broke away from her mother during a walk through the forest.
As hundreds of people silently made their way down a footpath in Tokai Forest, some wiped away tears and others clinged to flowers.
Tokai resident Heather Solomon said her family had always enjoyed runs in the forest, but that had changed.
Solomon said the whole community was been left shaken.
The mourners are placed flowers and messages of support on a fence that runs around the forest.
