Multiple reports describe an attack at a San Diego Islamic center in which three people are killed. The suspected shooter is identified as Cain Clark, 17. According to the reports, Clark left a written suicide note before the shooting. Authorities also allege that Clark took weapons from his mother before opening fire at the Islamic center, alongside another suspect identified as Caleb Vazquez, 18. The accounts state that the victims were killed during the Monday attack at the facility.

Other details cited in the reports include reactions from the shooter’s family. The reports describe Clark’s grandparents as being “shellshocked” and offering an apology related to the massacre. While the specific wording and context of the apology are not fully detailed across the sources provided, the reports consistently frame it as a personal statement in the aftermath of the killings.

The reports characterize the suicide note as expressing hate, but they do not provide additional corroborating information in the material shown here. Investigators’ motives and full circumstances are still part of the ongoing investigation.
