Four people were shot including a child and one person was killed Wednesday evening when gunfire broke out at a high school graduation in Fairfield, officials said. 

Officers with the Fairfield Police Department spoke with reporters Wednesday night and said four people had been shot at the Sem Yeto High School graduation at Fairfield High School around 7:15 p.m. and that an 18-year-old died from their injuries. The shooting happened at the ending of the ceremony in the parking lot in what police are calling a “large scale incident.” 

Fairfield Police Officer Michelle Belyea said the other people shot were ages 11, 20 and 25. All are being treated at the hospital and their current conditions were not known. 

No one was in custody and police were actively looking for the suspected shooter at about 9 p.m. 

At an 11 p.m. update from Belyea, she did not comment on whether anyone was in custody but said there was no threat to the community. 

Supervisor Wanda Williams said on social media Wednesday night that the shooting saddened her.

“My deepest condolences go out to the parents who lost their child, and to all the students, family members, and friends impacted during a time that should be filled with joy,” wrote Williams on Facebook.
