Preliminary investigations indicate that the incident started when a white SUV crashed through the fence surrounding the pipeline's right-of-way and hit a surface-level valve, according to the authorities.

The pipeline fire burned for four days and resulted in the death of one person and the injury of four others. After burning for four straight days, the owner of the pipeline that burst Monday in La Porte has released their first report on what chemicals could have been released into the air as a result.

An SUV entered Energy Transfer property Monday morning and struck a pipeline valve before a massive fire that was still burning into the night.
