Evacuation deaths
As an estimated 2.5 – 3.7 million people evacuated the Texas coastline, a significant heat wave affected the region. The combination of severe gridlock and excessive heat led to between 90 and 118 deaths even before the storm arrived.[40][41] Reports from the Houston Chronicle indicated 107 evacuation-related fatalities. Texas Representative Garnet Coleman criticized the downplay of the deaths in the evacuation and questioned whether the storm would be deadlier than the preparations.[58] According to local officials, the traffic reached a point where residents felt safer riding out the storm at home rather than being stuck in traffic when Rita struck.[40] Many evacuees periodically turned off their air conditioning to reduce fuel consumption as well as drank less water to limit the number of "restroom stops." According to a post-storm study, which reported 90 evacuation-related deaths, nine people perished solely as a result of hyperthermia. However, it was suspected that most of the 67 deaths attributed to heat stress were a combination of hyperthermia and chronic health conditions.[41] In addition to the heat-related deaths, 23 nursing home evacuees were killed after a bus caught fire on Interstate 45 near Wilmer.[41] The bus erupted into flames after the vehicle's rear axle overheated, due to insufficient lubrication, and ignited therapeutic oxygen tanks on board.[59] According to a resident near the site of the accident, there were three explosions.[60] Many of the passengers were mobility-impaired making escape difficult or impossible.[61] In June 2009, nearly four years after the fire, families of those who died in the accident won an $80 million settlement against the manufacturer of the bus and the company that provided the nursing home with it.[59]
