That’s where he is cleaning the headstones of Capt. S. L. Tibbitts and 1st Lt. Joseph H. Huau.  When he finishes, he writes their names on a sheet of paper and does some detective work to learn about them.

Hollowell tells The Florida Times-Union he comes from a military family and served in the U.S. Army. He says cleaning veterans’ graves helps the community and gives him a project.
