Four men accused of murdering teenager Franziska Blöchliger are due to appear at the Wynberg Magistrate’s Court on Tuesday.

The four are facing charges of murder, rape and robbery with aggravating circumstances.

A post-mortem found that Franziska, 16, was strangled and suffocated and had sustained blunt-force trauma when she was attacked in Tokai Forest on March 7.

Sand was found in her throat and she had been raped vaginally and anally.

She had arranged to meet her mother after going jogging in the popular recreational area by herself.

When Franziska did not arrive at the agreed meeting place, the family began to worry.

Her body was found during a search.

She had been robbed of her iPhone, watch, headset and diamond ring.

Prosecutor Kepler Uys said the accused were linked to the crime by witnesses and were found in possession of her belongings.

One of the accused men, Howard Oliver, intended to apply for bail.
