Idaho murders suspect Bryan Kohberger is back in court for pre-trial hearings ahead of his summer murder trial for the brutal stabbing deaths of four University of Idaho students.

Attorneys for the man charged in the deaths of four University of Idaho students have alleged police misconduct and flawed search warrants.

The judge presiding over Bryan Kohberger's case denied a motion filed by several media organizations requesting access to a closed-door hearing on Tuesday. District Judge Steven Hippler said the motion was received by the court "immediately prior" to the hearing at 10 a.

Bryan Kohberger and his attorneys will argue at hearings this week for excluding a host of evidence in the homicide case that is heading toward a summer trial.

The suspect in the murders of four University of Idaho students will face a judge for a hearing on whether or not his hearings set for later this week will be open to the public or not.

Defense attorneys for Bryan Kohberger want critical DNA evidence in the high-profile case thrown out, arguing that the way law enforcement used investigative genetic genealogy (IGG) to identify him as a suspect violated his constitutional rights.
