Milton A. Wilkins, 64, a friendly and popular figure in his Alexandria neighborhood, was fatally injured by a truck yesterday as he was crossing North Henry Street near his home.

Wilkins, a retired federal government worker whose right leg was amputated a decade ago because of severe circulatory problems and who recently underwent cataract surgery, was on his crutches when the accident occurred at 9:42 a.m.

Alexandria police said he was moving into traffic about 10 feet from a crosswalk at Princess Street when he was struck by a Howat Concrete Co. truck driven by Raymond Fox of 1625 Franklin St. NE, Washington. Henry Street carries southbound U.S. Rte. 1 through central downtown Alexandria and is heavily traveled.

Wilkins was pronounced dead a few minutes later at Alexandria Hospital. Police said the accident is under investigation and no charges had been filed.

Wilkins, who lived at 425 N. Payne, was recalled fondly yesterday by his neighbors and relatives.

"He spoke to people he didn't even know," said Sarah Meyers, a next-door neighbor.

Mabel Price, another neighbor, said Wilkins habitually took a morning walk, and yesterday she saw him stop and close his front yard gate moments before the accident. "He was all dressed up. He had on a red cap and dark trousers," Price said. "He was always cheerful and would shout, 'Good morning, Love.' "

"He was on his way over to see me," said Wilkins' sister, Eva W. Ladrey, who also lives on North Henry. "He came over most every day . . . . He was always coming over." She said her brother, who lived alone, was a veteran of World War II.
