Alleged Idaho killer Bryan Kohberger has sparked interest in cold cases in Pennsylvania and around the country, according to reports.
Former NYPD sergeant and professor at John Jay College of Criminal Justice, Joseph Giacalone told Fox News Digital that when investigators look into cold cases, they look at the clues in each case to see if there are connections.
“One thing about cold cases is you always look to see if your case is connected to any others, and the reason behind that is many times those cases will hold clues for each one,” he said. “If you can put them all together, you can put together the entire package.”
Giacalone added that not every suspect is a serial killer, which would make it difficult. In cases with similarities, investigators typically look into where the suspects have traveled, worked, and lived.
As CrimeOnline previously reported, Kohberger is facing murder and burglary charges in connection with the November 13 deaths of students Ethan Chapin, 20; Madison Mogen, 21; Xana Kernodle, 20; and 21-year-old Kaylee Goncalves.
The victims were found stabbed to death in their off-campus rental on King Road, near the University of Idaho. Kohberger then drove over 2,000 miles from Washington to his home state of Pennsylvania.
Giacalone said other killers have been known to flee the crime areas via interstates after committing crimes.
“Any time you have a suspect where you believe there could be companion cases, you look at every place they lived, every place they worked,” Giacalone added.
Meanwhile, investigators continue to look into unsolved crimes in the neighboring areas around the University of Idaho, while comparing clues from Kohberger’s case.
As of now, according to Pamela Lehman, a spokeswoman for the district attorney’s office in Lehigh County, no other unsolved cases in the area are connected to Kohberger.
“Nothing with respect to Kohberger has come about in our investigations of cold cases or unsolved cases to this point, but we always continue to investigate and pursue leads,” she told King 5 News.
Kohberger remains the sole suspect in the quadruple Idaho slayings.
