Drug overdoses took a deadly toll in Santa Rosa over the weekend. Police are investigating the deaths of four young people, and the hospitalization of two more, to see if they are connected to a man arrested for selling narcotics,

A Santa Rosa man accused of selling fentanyl-laced cocaine to local high school students who died over the weekend appeared in court Tuesday but has not been formally charged in their deaths.

A student was sent to the hospital for their injuries after they were stabbed by another student at a Santa Rosa high school on Tuesday, officials say. The school was placed on lockdown and students were escorted off campus to safety.
