Adan Mateo Llanos was 11 and attending a sixth-grade Zoom class from his Woodbridge, California home when he died on December 2, 2020, after suffering a fatal gunshot wound to the head. His microphone and camera were turned off during the class; his sister, in another room on her own online class, heard the shot and found him, then alerted a teacher who called 911. Adan was transported to a hospital but did not survive.

The family has insisted the shooting was an accident and said Adan showed no signs of depression or suicidal tendencies. The community and the school district offered support to the family, and a fundraising page was created to help pay funeral costs.

Are there people who knew Adan or who have information about how he might have accessed the gun?
