Idaho prosecutors say a man charged in the stabbing deaths of four University of Idaho students shouldn’t be allowed to offer an alibi defense unless he takes the stand himself during the murder trial later this year.

Jay Logsdon, North Idaho’s state public defender and co-counsel for the case’s defense, will be replaced for Kohberger’s capital murder trial, a Thursday court order said. Taking Logsdon’s spot is a Northern California attorney who specializes in DNA and previously testified as a paid consultant for the defense.
