The family of the suspect in the Nov. 13 fatal stabbings of four University of Idaho students have finally spoken out after his arrest on Friday. 

Bryan Christopher Kohberger, 28, was taken into custody by local police and the FBI at 1:30 a.m. Friday in eastern Pennsylvania on a warrant charging him with four counts of murder and burglary for the deaths of Ethan Chapin, 20, Xana Kernodle, 20, Kaylee Goncalves, 21, and Madison Mogen, 21.

"We have fully cooperated with law enforcement agencies in an attempt to seek the truth and promote his presumption of innocence rather than judge unknown facts and make erroneous assumptions," Kohberger's family said in a statement released by his public defender, Jason A. LaBar. 

The family said they "will continue to let the legal process unfold and as a family we will love and support our son and brother."
