Attorneys working to present their case in the murder trial of Bryan Kohberger this summer are zeroing in on the timeframe before and after four University of Idaho students were slain in an ambitious effort to convince a judge to discard or allow certain evidence.

The creepy selfie Bryan Kohberger took giving a thumbs up hours after allegedly slaughtering four University of Idaho students was taken as a sick “trophy” for the accused killer, a father of one of the victims claims.

Prosecutors said they have evidence that the man charged in the stabbing deaths of four University of Idaho students bought a knife and knife sheath online in the months before the killings, newly released court documents show.
