Near the beginning of third period, Principal April Scott directed teachers to take attendance immediately, notifying them of the situation via email. Though authorities have not yet verified if the victim was an MVHS student, the sheriff’s department reported the fatally wounded biker was a juvenile.

Students who witnessed the accident or need support are being asked to see executive assistant Monique Franzino in the main office, who will arrange for them to see a counselor or administrator.

Senior Drew Jones reported seeing police cars, ambulances and police caution lines on the way to school while stuck in traffic caused by the accident. With the intersection completely closed, traffic was redirected down Bubb Rd. In a separate announcement, Scott later directed student to avoid 7-Eleven during lunch.

It is not yet clear where the truck was headed or coming from, but according to Cupertino Municipal Code Chapter 11.32, trucks are not permitted on McClellan Rd. if they are not delivering goods or taking “the shortest and most direct route to the nearest truck traffic route or other unrestricted highway.” McClellan Rd. connects De Anza Blvd. and Foothill Blvd. but Stevens Creek Blvd. connects both roads as well and is also a permitted truck route.

Update: Authorities have verified that the victim attends MVHS.
