WATERLOO | Preliminary results from Friday’s autopsy of a Waterloo Navy veteran who was found unconscious on Memorial Day are inconclusive, according to police.
“It’s undetermined at this point,” said Lt. Michael McNamee with the Waterloo Police Department.
A passerby discovered Dennis Dwaine Washburn, 69, in the area of the former Longfellow Elementary School in the early morning hours of May 26, not long after he was seen leaving a nearby tavern. He never regained consciousness and died in the hospital June 4.
Washburn had suffered severe head injuries. But investigators were unable to determine what caused the injuries, McNamee said Monday.
“He died from the injuries sustained, but they haven’t determined, at this point, how the injuries were sustained, if he was assaulted or if he just fell. It sounded like the injuries could be consistent with either,” McNamee said.

He said another pathologist will review the autopsy in the near future in an attempt to determine the manner of death.
Family members said Washburn’s wallet was found some distance from where he was located. A crate of groceries he bought was found with his walker.
Washburn was seen leaving The Jet Lounge on West Parker Street around 9 p.m. May 25. He was found about half a mile away near the school on Edwards Street around 12:30 a.m. the following morning.
