Fans of CSI: Miami and NYPD Blue have a habit of looking beyond the screen. Once a show ends, curiosity about the actors often turns toward their personal lives — their families, their children, and what happened after the cameras stopped. That’s likely what brings most people to search for Marquez Anthony Caruso.
This article covers what is publicly confirmed about Marquez, who his father David Caruso is, what is known about his family, and why so little information exists about him beyond basic records.
The Basic Facts About Marquez Anthony Caruso
Marquez Anthony Caruso was born on September 15, 2005, in the United States. His father is actor David Caruso, and his mother is Liza Marquez. He holds American nationality.
His name appears primarily in genealogical records and a small number of personal social media posts. There is no evidence that he is a public figure, an entertainer, or anyone who has sought out the spotlight in any way.
A Facebook post from 2019 — shared by what appears to be a classmate marking his 14th birthday — described him as “not just a classmate” but “a brother, a teammate.” That kind of mention paints a picture of a normal private life, not a celebrity one.
Most searches for his name land on genealogy profiles, such as a MyHeritage record that confirms his parentage, birth date, and nationality. That is essentially the extent of his documented public presence.
His Father — David Caruso’s Career and Public Profile
The reason most people search for Marquez is simple: his father is a well-known American actor. David Stephen Caruso was born on January 7, 1956. He is a retired actor and producer, best known for two significant television roles.
The first was Detective John Kelly on NYPD Blue, which launched in 1993. The show was a critical hit, and Caruso’s performance earned him wide recognition early in his career. However, he departed the series after its first season — a decision that, at the time, drew considerable media attention.
After a period of film work that didn’t quite match the momentum of his television success, Caruso returned to television in a big way. He took on the role of Lieutenant Horatio Caine on CSI: Miami, the long-running CBS procedural drama. The show ran from 2002 to 2012, giving Caruso over a decade in a signature role that became closely tied to his public identity.
Since CSI: Miami ended, Caruso has maintained a much lower profile. He is generally described as retired from acting. Fans who followed his career through both shows sometimes go looking for information about his personal life — and that’s often how they find references to Marquez.
Marquez’s Mother and His Parents’ Relationship
Liza Marquez is identified in public sources as David Caruso’s former girlfriend and the mother of his children Marquez and Paloma. Beyond that, very little about her personal life is documented publicly.
The relationship between Liza Marquez and David Caruso has occasionally appeared in media coverage due to a legal matter. In April 2009, Liza Marquez filed papers against Caruso citing fraud-related claims. That filing is a matter of public record and is noted in Caruso’s Wikipedia entry.
It’s worth keeping that detail in its proper place. It is background context — a reason why the relationship sometimes surfaced in news coverage — not something that defines Marquez or his upbringing. The focus here is on the family structure, not the legal details between the adults involved.
Marquez’s Siblings and David Caruso’s Broader Family
Marquez has a sister named Paloma. Both Marquez and Paloma are the children of David Caruso and Liza Marquez.
David Caruso also has a daughter named Greta from a previous relationship, which makes Marquez part of a broader blended family. Greta is mentioned in public sources in connection with David Caruso’s family history, but like Marquez and Paloma, she is a private individual.
The picture that emerges is of a father with children from more than one relationship — a family structure that is common and unremarkable. None of the children appear to have pursued public careers or sought media attention.
Why Celebrity Children Often Stay Out of the Public Eye
It is completely normal for a celebrity’s child to have almost no online presence beyond a birth record or a genealogy database entry. Fame doesn’t automatically transfer from parent to child, and many children of well-known people actively avoid public attention — especially while growing up.
Marquez was born in 2005, which means he spent his childhood and teenage years in an era of heavy social media use. Yet his footprint remains minimal. That suggests a deliberate choice — either by his parents, by Marquez himself, or both — to keep his life private.
Genealogy platforms like MyHeritage pull from public records to create biographical profiles. That’s why Marquez’s name, birth date, and parentage appear in searchable databases even though he has never been in the news himself. It doesn’t mean he is seeking attention. It simply means that basic civil records are part of the public domain.
The same is true for many celebrity children. A fan watching CSI: Miami reruns might wonder whether Horatio Caine’s actor has kids. A quick search leads to Wikipedia, which mentions Marquez and Paloma. From there, a MyHeritage profile fills in a birth date. The trail ends there — because there isn’t more to find.
That absence of information is itself informative. It tells you that Marquez Anthony Caruso is, by all accounts, living a private life — the kind of life most people simply call normal.
A Note on Name Confusion
If you’ve searched around for “Anthony Caruso” and found results about an older actor, those results are unrelated to Marquez. There was a mid-20th-century American character actor named Anthony Caruso (1916–2003) who appeared in television productions including The Addams Family. He has his own documented career and biography.
Genealogy databases and general searches can return mixed results when common names overlap. Marquez Anthony Caruso is a 21st-century individual — born in 2005, the son of David Caruso — and has no connection to earlier entertainers who share parts of the same name.
What We Actually Know, and What We Don’t
To summarize what is publicly confirmed about Marquez Anthony Caruso:
- Full name: Marquez Anthony Caruso

- Nationality: American
- Father: David Caruso, retired actor
- Mother: Liza Marquez

Final Thoughts
Marquez Anthony Caruso is, first and foremost, a private person. His connection to David Caruso is what brings people to search for his name, and that’s a perfectly understandable starting point for curiosity.
David Caruso built a real career across decades of television — from the gritty streets of NYPD Blue to the sun-soaked crime scenes of CSI: Miami. It makes sense that fans who followed that career would eventually wonder about the man behind the roles, including his family.
What we know about Marquez is limited, and that’s fine. Some people simply aren’t public figures. He appears to be one of them — and there’s nothing wrong with that.
