Grinnell, Iowa postal worker Dwayne Kriegel was a beloved member of his community after delivering mail for over 30 years.

Sadly, Kriegel passed away on Tuesday following an allergic reaction to wasp bites, reports WHO-TV.

According to his wife, Tammy, Krieger had developed the wasp allergy just a couple of years ago.

Krieger was life-flighted to Des Moines, but passed on Tuesday. He was reportedly without oxygen for fourteen minutes.

Krieger's legacy of kindness lives on, as he was able to donate his organs.

Tammy is reminding people to be aware of wasps and bees that could be near their mailbox or plants., especially when children could be in the area.
