Days after an explosion at an Oak Cliff apartment complex killed three people and wounded five others, several key questions remain unanswered.

Before striking a pipeline, causing a natural gas leak and subsequent explosion, an engineering firm did follow proper protocol to begin work at a Dallas apartment building.

An investigation led by the National Transportation Safety Board is still underway to answer questions about what went wrong.
