I am completely new to this, but have some thoughts:
If

Is there a way to search military records by date of birth? specifically
September 24? and three days prior?
Birthdays are periods of increased (suicide) risk for men aged 35 and older
Birthdays are periods of increased risk for men aged 35 and older in the general population and in those receiving mental health care. Raising health-care professionals' awareness of patient groups at greater risk at this personally significant time may benefit care planning and could facilitate...

I also think
PR could be for Puerto Rico/Porto Rico.
As provided by Mfliesh - in the hand written note from Marathon County public records, his complexion is described as medium. Puerto Rican's are tri-racial and have skin tones from white to black.
The
Statue of Liberty can symbolize many things, including American patriotism,
New York City, and the enduring friendship between the people of
France and the people of America - symbolizing abolition, democracy, and a beacon of hope for immigrants.
Puerto Ricans immigrated to the USA starting in the late 19th century, primarily as political exiles and
intellectuals seeking independence from Spain, with communities forming in New York City by the 1890s, long before they were granted citizenship in 1917.
(Canadians immigrants used official land border crossings or other ports like Halifax and Quebec City. Ellis Island was primarily for large scale processing of European immigrants arriving by ship.)
New York City's 77th Sustainment Brigade/77th Infantry Division/The
Statue of Liberty Division/The Melting Pot Division used The Statue of Liberty as their unit insignia. This unit was know for its exceptional diversity including Puerto Ricans.
(A Lady Liberty tattoo was also popular among the general military during WWI too, especially for those sailing to Europe - being the last glimpse of home and hopefully the first upon their return.)
The 15th
New York National Guard Regiment/369th Infantry Regiment/Harlem Hellfighters was a black segregation unit - that included Puerto Rican soldiers and white officers - served under
French command in WWI and had a
shipping vessel as part of their insignia.
Both units saw combat in The Meuse-Argonne Campaign.
Starting in France, on September 26, 1918, this was the the deadliest and largest land offensive in US military history, lasting until armistice on November 11, 1918.
On
September 29, 1918, the 369th captured the town of Séchault, France, but suffered some of the heaviest losses of any American regiment in the process.
Coming under attack on
October 2, 1918, soldiers of the 77th Division would become known as the Lost Battalion. 554 American soldiers were surrounded, outnumbered, and fought for their lives for nearly 6 days. Under the leadership of Charles W. Whittlesey they held their position. Only 194 survived unwounded. Notably, Whittlesey died by suicide three years later.
Probably not helpful in indentification, but interesting nontheless:
Many minorities not only enlisted, but pursued combat in WWI to prove their loyalty and earn full citizenship. Along with challenges like widespread unemployment, inadequate healthcare, poor housing, social isolation/civilian reintegration, and substance abuse faced by most soldiers, minorities returned to find the fight for democracy abroad had not translated to equality at home.
The doenetwork shows:
Estimated Date of Death: Unknown
he was found 09/24/1930 and estimated to have died 4-6 hours before
State of Remains: Not recognizable - Partial skeletal parts only.
he was found 4-6 hours after death
Eye Color: Unknown
this would be known (just not to the general public)
Fingerprints: Unknown
known, not matched
The military started fingerprinting prior to WWI, so perhaps there would be a match, but according to the following a webpage, it is a little more complicated.
Fingerprint identification of John and Jane Doe cases.

If prints are digitized/nationalized over time, perhaps a re-submission in the future will yield results.
