Matthew Foerster, 26, is facing a number of charges including first-degree murder in the slaying of 18-year-old Taylor Van Diest.
Members of Taylor Van Diest's family will be in the courtroom to hear if Foerster is released.
The request for bail is one of two applications before a B.C. Supreme Court judge at the Kelowna court house Thursday. Foerster's lawyer is also applying to have the trial moved to Vancouver.
The Crown wants the proceedings held in Kelowna or Kamloops.
Foerster was arrested in April 4 in Collingwood, Ont., in connection with Van Diest's killing. His father, Stephen Foerster, was arrested in B.C. the same day and charged with obstruction of justice.
Van Diest went to meet friends the night of Oct. 31, 2011, but did not arrive. She was found later near railroad tracks in Armstrong, severely beaten, and died later in hospital.
Foerster is also charged with sexually assaulting a Kelowna escort, and with a violent home invasion of a teen in Cherryville, B.C.
His lawyer has already waived his right to a preliminary hearing on those charges and is expected to do the same on the murder charge Thursday
