Idaho murder suspect doesn't break a sweat as he's perp-walked through Monroe County Courthouse under heavy guard

• A man accused of killing four University of Idaho students made his first court appearance Tuesday.
• He was arrested in connection with the deaths of four University of Idaho students.

The man accused of murdering four college students in Idaho was escorted through the Monroe County Courthouse by heavily-armed officers in Stroudsburg, Pennsylvania, for a brief appearance Tuesday.

While the suspect walked through the courthouse in handcuffs, he wore a heavy black vest under his red-orange jumpsuit, appearing cool-headed and offering no real sign of his emotions as officers guided him to his hearing.

Video released of the seven Monroe County Sheriffs escorting officers appears to show one of them walking behind the suspect holding a rifle.

The suspect was arrested in Pennsylvania on December 30 in connection with the November 13 stabbing deaths of 21-year-old Kaylee Goncalves, 21-year-old Madison Mogen, 20-year-old Xana Kernodle, and 20-year-old Ethan Chapin in an off-campus apartment in Moscow, Idaho. He is currently facing first-degree murder charges.

At the time of his arrest, the suspect was a Ph.D. candidate at Washington State University who once asked users on Reddit how emotions influence how people commit crimes, a nearly-year-old post showed.

The suspect is being held without bond in Pennsylvania and also faces one count of felony burglary.

During his court appearance — where the 28-year-old suspect waived his extradition rights to face murder charges in Idaho — he appeared ashen and downcast, Insider's Laura Italiano reported.

He is expected to be transported to Idaho within the next 10 days.

Video prior to his arrest released on Tuesday show that the suspect was pulled over twice by police officers in Indiana on December 15. Each time he was let go by police, the body camera footage shows.

A lawyer for the suspect has said he maintains his innocence.
