Roll of Honor
Incident
Officer Seuis was killed when his police motorcycle was struck by a tractor-trailer on I-238, just north of East 14th Street, in Castro Valley at about 2:10 pm.
He was transported to a local hospital but succumbed to his injuries.
The tractor-trailer fled the scene but was stopped by a California Highway Patrol officer approximately 10 minutes later and the driver was arrested. The driver, an illegal alien, was charged with felony hit and run. The charges were dismissed one year later due to insufficient evidence.
Officer Seuis had served with the Oakland Police Department for 16 years.
Survivors
He is survived by his wife and two daughters.
