Robert Mancuso Missing Since August 31
Robert Mancuso disappeared while visiting Paris on Monday afternoon.
According to the family alert, Robert became separated from the people he was travelling with and was last seen near the Louvre Museum at approximately 4:00 p.m.
Family members immediately began sharing his photograph and description online, asking anyone in Paris to help locate him.
The concern is particularly urgent because Robert has Alzheimer’s disease.
Relatives say he may appear confused or disoriented and could have difficulty explaining who he is, where he is staying or how to contact his family.
French Missing-Person Organisation Lists Robert Mancuso
The search is no longer limited to family posts on social media.
France’s Assistance et Recherche de Personnes Disparues, or ARPD, now lists Robert Mancuso as an active missing-person case.
The organisation identifies him as 65 years old and states that he disappeared on August 31, 2026, in Paris.
Its listing broadens the search area beyond the Louvre itself to include the Louvre, Notre-Dame and Latin Quarter sectors of central Paris.
That independent listing is significant because it confirms that the family’s appeal has reached an established French missing-person organisation.
As of the latest available listing, Robert has not been marked as found.
What Does Robert Mancuso Look Like?
Robert is described as a man in his mid-60s weighing approximately 180 pounds, or 82 kilograms.
He has dark hair with grey along the sides and was clean-shaven when he disappeared.
At the time he was last seen, Robert was reportedly wearing:
- White shorts
- A blue short-sleeve button-down shirt
His family says Robert did not have his phone or wallet with him.
That may make it harder for him to contact relatives, return to his accommodation or show identification if approached by authorities or members of the public.
Alzheimer’s Makes Search Especially Urgent
Robert’s Alzheimer’s diagnosis is one of the most important details in the missing-person appeal.
His relatives have warned that he may appear confused and may not be able to identify himself.
Don Mancuso, who described Robert as his cousin, said Robert wandered away from his group while in Paris.
Laura Marinelli, Robert’s niece, also appealed publicly for help, saying her uncle had been missing for more than 24 hours and asking anyone with connections in Paris to spread the information.
Family members including Laura, Peter, Sara and Julia have reportedly been involved in efforts to find him.
Search Expands Around Central Paris
Although Robert was initially reported missing near the Louvre, people searching for him should not assume he remains in the immediate museum area.
A person who is walking and disoriented can travel a considerable distance over many hours.
The ARPD alert specifically references the Louvre, Notre-Dame and Latin Quarter area.
These are heavily visited areas containing hotels, cafés, museums, metro stations, pharmacies, restaurants and pedestrian routes.
Robert’s family has therefore asked that the alert be shared widely with people working throughout central Paris, including hotel employees, taxi and rideshare drivers, restaurant staff, museum workers, tour guides, pharmacists and hospital staff.
Family and Friends Plead for Help
Friends of the Mancuso family have amplified the appeal internationally.
Jen Donati shared the alert and asked contacts in Paris to watch for Robert, noting that he has memory difficulties.
Anna Gilbert similarly appealed to anyone who knew people currently in Paris to share his information.
Laura Marinelli later said her uncle remained missing after approximately 24 hours and stressed the family’s need to get the alert in front of French news organisations and local residents.
The repeated appeals demonstrate the urgency felt by relatives as the search continues.
What to Do if You See Robert Mancuso
Anyone who believes they have seen Robert should avoid simply posting the sighting online and moving on.
If it is safe to do so, the family asks people to remain nearby so Robert does not wander away again.
French police can be contacted by dialling 17.
The European emergency number 112 can also be used.
A suspected sighting should include as much useful information as possible, such as the exact location, time, direction Robert was walking and what he was wearing.
Because he may be disoriented, a calm and reassuring approach is preferable while emergency services are contacted.
Is Robert Mancuso Still Missing?
As of the latest available information, Robert Mancuso remains listed as missing by ARPD.
The organisation’s current Paris search results continue to identify him as a 65-year-old man who disappeared on August 31 in the Louvre / Notre-Dame / Latin Quarter sector.
No reliable report indicating that he has been found has surfaced in the latest searches.
That status could change quickly, so updates from his family, French authorities or ARPD should take priority over older social-media posts.
