Authorities are investigating cold cases for potential links to Idaho murder suspect Bryan Kohberger

Authorities in two Pennsylvania counties where Idaho murder suspect Bryan Kohberger went to college are reviewing past cold cases to see if descriptions of suspects in those crimes match those of the accused killer.

“Your natural question is to start asking yourself, ‘Is this guy wanted? ‘” Northampton County District Attorney Terence Houck told KING-TV, NBC’s Seattle affiliate. “Is his name there?” Did he do something here in (my) county?

Mr Houck said his staff had searched criminal databases using the height, weight and other characteristics of Mr Kohberger – who is the only suspect in the November murder of four University of Idaho – to see if it was reported in unsolved crimes. Mr. Kohberger attended Northampton Community College in Bethlehem, Pennsylvania.

The prosecutor said his team had found nothing so far linking Mr. Kohberger to other crimes. However, Mr. Houck acknowledged that Mr. Kohberger may have attended Northampton Community College’s satellite campus in neighboring Monroe County.

Jim Martin, the Lehigh County district attorney, where the murder suspect studied criminology at DeSales University, also reviewed county police records for Mr. Kohberger.

All that was found was a 911 call where Mr Kohberger called police to help get him to his car which was behind a locked door.

Mr. Kohberger, a doctoral student in criminology at Washington State University, was arrested at his parents’ home in Pennsylvania on December 30.

He was extradited days later to Idaho, where he was charged with four counts of first-degree homicide in the Nov. 13 murders of 20-year-old Ethan Chapin; Xana Kernodle, 20; Kaylee Goncalves, 21; and Madison Mogen, 21. He was also charged with one count of burglary.

A combination of cellphone recordings, surveillance footage from his car and DNA found on a knife sheath at the scene led police to Mr Kohberger, according to a probable cause affidavit released following his January 5 hearing. He has not yet entered a plea.

His next court appearance will be in June. He is being held in Latah County Jail.
