A Texas firefighter was discovered dead in a Cancun hotel where he and his wife were celebrating their 10th wedding anniversary, but his family doubts that it was an accident.

After Mexican officials reported his body was found trapped in a hotel bathroom window early on Monday, July 19, the family of Elijah Snow, an eight-year firefighter with the Arlington Fire Department, believed that he might have been kidnapped and murdered.

Officials stated that there was no sign of violence at the scene. However, the investigation is ongoing, and the U.S. Embassy in Mexico is keeping a close eye on the case.

On the other hand, Snow’s family hired a local attorney who received crime scene images showing bruises over most of his body, according to KTVT. His family now believes he was kidnapped and beaten before being killed.

According to the news station DFW-TV, Snow had traveled to an all-inclusive resort in the popular tourist destination of Cancun with his wife, Jamie, last week.

Snow and his wife were drinking at a hotel bar when his wife returned to their room, and he stayed behind Snow’s father-in-law, Randy Elledge, told a local CBS affiliate. Elledge said Snow’s wife woke up about 4 a.m. and alerted authorities after noticing he wasn’t there.

NBC News reported that Snow was trapped in a hotel bathroom window and may have suffered mechanical asphyxiation.

The hotel where Snow’s body was found is different from the one he had been staying at with his wife, and no reason for that has been forthcoming.

On Friday, Snow’s remains were returned to North Texas from Cancun. His funeral will be held at Arlington on Tuesday.

“You’re supposed to be safe there,” Randy Elledge, Snow’s father-in-law, told the outlet. “You’re at your resort, all inclusive, and have no intentions of leaving so you’ll be safe. And you’re not safe there.”

The Arlington Professional Firefighters, a labor union that represents Arlington firefighters, said Snow “was an outstanding firefighter as well as a dedicated public servant,” NBC 5 reported.

“The Fire Department will take all necessary steps to ensure that Elijah’s family is properly supported throughout this difficult time,” the union said. “Our prayers are with his family.”
