A 40-year-old El Centro man died Sunday of injuries following a bee attack that occurred outside his Bowker road home, authorities said.

An autopsy is pending to determine if Mario Rosales died directly from the bee stings he suffered as he tried helping his 78-year-old father, Gonzalo, who was being attacked. Rosales and his father were trying to remove a fallen tree branch and inadvertently knocked over a trash barrel that contained a bee hive.
