Umeshkumar Thakkar was found unresponsive in his delivery vehicle as an extreme heat warning covered the North Texas area.
LITTLE ELM, TX — A 58-year-old U.S. Postal Service letter carrier died while working his route in Little Elm, prompting investigations by postal officials and federal workplace safety authorities.
Umeshkumar Thakkar was found unresponsive inside a postal delivery vehicle near the 1600 block of Thornhill Lane on Monday, July 20. The Little Elm Fire Department said crews were sent to the area at about 2 p.m. and attempted CPR, but Thakkar could not be revived.
The official cause of death had not been released as of Friday. Authorities have not determined whether heat contributed to his death, though an extreme heat warning was in effect when emergency crews responded. The investigation remains open.
The National Rural Letter Carriers’ Association identified Thakkar on Thursday. The union said he had worked as a part-time rural carrier since 2022. The organization represents rural letter carriers and other postal employees across the country.
Don Maston, president of the association, said the union was deeply troubled by Thakkar’s death. He said postal employee safety must remain a priority as carriers work through dangerous summer temperatures in many parts of the country.
The Postal Service said it was saddened by the loss of a member of its workforce. The agency said its thoughts were with Thakkar’s family, friends and colleagues and that counseling would be offered to employees at the Little Elm Main Post Office.
Customers along the route noticed that Thakkar’s vehicle had remained in the same place for an extended period and checked on him, Maston told NBC 5. Emergency responders were then called to the residential street, where the postal truck was parked.
Several residents said the emergency response shook the neighborhood. Witnesses described seeing police vehicles, an ambulance and a firetruck near the mail vehicle. Some said the incident raised concerns about people whose jobs require them to spend long periods outdoors during severe heat.
Union officials urged carriers to follow established heat-safety procedures, drink water, recognize signs of heat-related illness and watch for problems among co-workers. Those comments did not establish that heat caused Thakkar’s death, which remains a matter for investigators and medical authorities.
The Occupational Safety and Health Administration is investigating the workplace death, according to NBC 5. The Postal Service is conducting a separate investigation into the circumstances surrounding the incident. No timetable has been announced for the completion of either review.
