Law enforcement has arrested a suspect in the murders of the four University of Idaho students who were killed at an off-campus house.

Authorities apprehended a 28-year-old man, Bryan Kohberger, on Friday morning, according to law enforcement sources. The suspect was tracked down to Pennsylvania, where a SWAT team entered the location where he was staying to take him into custody.

Kohberger was apprehended by the Pennsylvania State Police and FBI in Monroe County, an eastern area located in the Pocono Mountains.

He is being held for extradition to Idaho for first-degree murder, according to arrest documents. The suspect appeared before a judge on Friday morning.

Idaho University students Kaylee Goncalves, 21; Madison Mogen, 21; Ethan Chapin, 20; and Xana Kernodle, 20, were attacked on Nov. 13 at a three-story rental home off-campus.

The four college students suffered multiple stab wounds, and some of the victims appeared to have defensive wounds. Autopsies suggested all four were likely asleep at the time of the attack.

Kernodle, who was dating Chapin, lived in the home with Mogen, Goncalves, and two other roommates. The victims were on the second and third floors of the home.

Police believe the two other roommates, who were on the ground floor and survived, slept through the attacks.

Since the murders, police have received an estimated 20,000 tips through various channels, including phone calls, emails, and digital media submissions.

"Investigators believe someone has information that adds context to what occurred on the night of the murders and continue requesting additional pictures, video, and social media content," police said in a previous statement.

"Whether you believe it is significant or not, your information might be one of the puzzle pieces that help solve these murders."

Moscow police officers, members of the Idaho State Police, Moscow city leaders, and University of Idaho officials will hold a news conference at 1 p.m. local time (4 p.m. ET) on Friday to share updates on the case.
