It's been nearly seven weeks since four University of Idaho students were brutally

stabbed to death, likely as they slept, leaving some students to afraid to return would

have been a quiet college campus.

But late today, authorities arrested a suspect in the killings.

I'm Pam LaBralne and for Anderson tonight and I'm just getting new information from

a source familiar with the investigation we're learning that the suspect actually drove

cross-country from Idaho to his parents' home in Pennsylvania and arrived there around

Christmas.

The source told me it was a combination of DNA found at the crime scene as well as the

car that helped authorities figure out who their suspect was last week.

And that is when law enforcement got together to sort all this out and then they made the

arrest culminating in everything happening today.

So they announced the arrest of Brian Coburger.

This right here is his booking photo.

He is a graduate student from Washington State University, less than 10 miles from where

the four victims attended school.

He was arrested in Pennsylvania on four counts of murder in the first degree plus a separate

charge of felony burglary.

As we said, sources tell CNN, his DNA was matched to DNA recovered at the scene of the

deaths.

And tonight, law enforcement is asking for the public's help with uncertainty still surrounding

the case, including motive and location of the murder weapon.
