A State Fire Marshal's Office report on a hotel fire that killed four Houston firefighters found communication problems between first responders at the scene.
The report also mentioned an incomplete assessment of the structure that could have given those at the scene more information on how to best battle the blaze.
However, the report released Friday also said its final analysis doesn't suggest the firefighters who were killed and injured "failed to perform their duties as trained."
Houston Fire Chief Terry Garrison said he's pleased with the report and that its conclusions are similar to those reached by an internal fire department probe.
The May 31, 2013, fire was the deadliest day in the department's 119-year history. In addition to the four deaths, another 12 firefighters were injured.
