Bryan Kohberger sentencing: Idaho college student killer sentenced to life in prison

New video shows Bryan Kohberger's family visiting him in custody on the eve of his sentencing.

Kohberger's parents attended his change of plea hearing on July 2, their first time in court with their son since his arrest in Pennsylvania more than two years ago. Attorneys for the Kohbergers said in a statement at the time, "The Kohbergers are asking members of the media for privacy, respect, and responsible judgment during this time. We will continue to allow the legal process to unfold with respect to all parties."

President Donald Trump weighed in on the case on social media Monday, saying he thinks Bryan Kohberger should be required to reveal a motive.

"I hope the Judge makes Kohberger, at a minimum, explain why he did these horrible murders," he wrote. "There are no explanations, there is no NOTHING. People were shocked that he was able to plea bargain, but the Judge should make him explain what happened."

The family of 21-year-old victim Kaylee Goncalves thanked Trump for "pushing for justice," saying in a statement to ABC News, "A confession without clarity does not bring peace."

"If the defendant is permitted to live, the bare minimum he owes us, and this country -- is an explanation," the family said.
