According to court documents, Irving confessed to the shooting.

Investigators say he told police he used a handgun that was found in his bag to shoot Beam inside the Laney College field house.

And that is where Beam worked every day as the athletic director.

I know that he appeared in court.

What happened there?

He did appear in court.

Irving made his first appearance, but he did not enter a plea.

He stood next to his public defender while wearing a padded safety vest, which is something the jail system uses when there are concerns about a person harming themselves.

He said very little, and then the judge scheduled his next hearing for December 16th.

Well, Marissa, do police have any sense of why he may have done this?

No.

Yeah, that seems to be the big question in this.

Police have only said that Irving came to campus with intention, that the two men were aware of each other in some capacity, but they were not closely connected.

So beyond that, officials have not released any additional details about why this might have happened.

Yes.

The front rows were filled with Beam's family, friends, and one very recognizable face was there as well.

NFL running back and Oakland native Marshawn Lynch attended the hearing to support Beam's loved ones.

It was a class of criminology students at the University of Arlington.

And investigators are saying that these students uncovered evidence that has led to an arrest in the 1991 murder of 25-year-old Cynthia Gonzalez.

The Arlington Police Department had partnered with the class for the semester and gave the students access to hundreds of pages from the old case files.
