On Tuesday, a septic tank truck collided with a Ford Explorer SUV sport-utility vehicle killing seven. The crash took place near Modesto, California sending both vehicles into the Delta-Mendota canal.

Investigators are still trying to determine the cause of the accident while the seventh passenger remains missing and is presumed to be dead. United Site Services, Inc., a Massachusetts Corporation owns the septic tank truck and has not released any information.

Our deepest sympathies and condolences to the families of those who have lost loved ones as a result of this horrific accident. Anytime commercial size vehicles are involved in accidents with passenger vehicles, the end result has a possibility of ending tragically like this very accident. It is important that a thorough and diligent investigation be conducted immediately to determine the causes of this accident.
