A 90-year-old man doing yard work at his family's home in Rio Hondo died Tuesday after a swarm of bees attacked him.

Valeriano Bautista – a witness to the incident – said he was doing yard work with the man, who was on a tractor when the bee attack occurred.

“I came to the truck to go all the way to the back and I saw that he had a lot of bees," Bautista said. “You couldn't do anything, he had too many bees - and I went right there and the bees were coming towards me."

The victim was later pronounced dead on scene. 

Firefighters searched the property and found a large bee hive in an old boat.

The Cameron County Public Health department and Cameron County Sheriff’s Office are investigating the incident.
