California high school graduation shooting kills teen, injures child and two others

An 18-year-old student was killed and three other people, including an 11-year-old child, were wounded in a shooting Wednesday evening during a high school graduation event in Northern California, police said.

The shooting occurred during a Sem Yeto High School graduation ceremony held at Fairfield High School, according to authorities.

Fairfield Police Officer Michelle Belyea said three victims who suffered gunshot wounds were ages 11, 20 and 25. The 18-year-old student later died from injuries sustained during the incident.

The surviving victims were receiving medical treatment, Belyea said.

Police have not released information about a suspect and said additional updates are expected later Thursday.

Sem Yeto High School is a continuation school within the Fairfield-Suisun Unified School District.
