The Postal Service is investigating after Umeshkumar Thakkar became unresponsive inside his vehicle during a period of intense North Texas heat.
LITTLE ELM, Texas — A 58-year-old U.S. Postal Service letter carrier died after becoming unresponsive inside his postal vehicle while working a route in Little Elm, authorities and his family said.
Umeshkumar Thakkar collapsed Monday, July 20, during his shift, according to information provided by his family and emergency officials. The Postal Service has not said what caused his death or whether the extreme temperatures across North Texas contributed to it. The agency said the circumstances remain under investigation.
Surveillance video recorded near Thornhill Lane and Graystone Drive showed Thakkar’s postal vehicle stopped with its hazard lights flashing at about 12:20 p.m. Little Elm Fire Department crews were called at about 2 p.m. after someone reported that a postal worker had passed out inside a vehicle and was not responding.
Emergency personnel performed CPR, but Thakkar could not be revived. He was pronounced dead after responders arrived. Officials have not released additional medical findings, and no determination about the cause or manner of death had been announced as of Thursday.
The Postal Service expressed condolences to Thakkar’s family, friends and colleagues and said counseling would be available to employees at the Little Elm Main Post Office. Thakkar was represented by the National Rural Letter Carriers’ Association, which said its members were heartbroken by his death.
“On behalf of NRLCA’s 130,000 members nationwide, we extend our deepest condolences to Umeshkumar’s family, friends, and co-workers during this difficult time,” the association said in a statement.
Neighbors said Thakkar’s vehicle had been stopped in the area before emergency crews arrived. Manny Ortiz said he noticed the postal vehicle near his mailbox when he returned from a gym. Police officers and firefighters arrived a short time later and gathered near his home.
“They said the postman passed out,” Ortiz said. “They shouldn’t be working in this heat.” Another neighbor, Ximena Ayala, said she saw several patrol vehicles and fire trucks. She also saw someone looking inside the postal vehicle while speaking frantically on a phone.
North Texas was experiencing triple-digit temperatures when Thakkar died. A heat advisory covered the region Monday, and dangerous conditions continued later in the week. The National Weather Service forecast heat index readings above 100 degrees for Little Elm, but investigators have not connected the weather to Thakkar’s death.
The Postal Service investigation remained open Thursday. Officials had not released an autopsy result or said when a final determination about Thakkar’s death might be available.
