This article explores the various men named as potential fathers, the latest 2025 updates involving the Anthony family, and the enduring theories that continue to captivate true crime enthusiasts.

The Candidates: Men Named as Caylee's Potential Father

Over the course of the investigation and the subsequent media frenzy, Casey Anthony offered several conflicting accounts of her daughter’s paternity. This list details the most prominent men publicly linked to the mystery of Caylee's biological father.

Jesse Grund: The Early Suspect

Jesse Grund was Casey Anthony's fiancé at the time of Caylee's birth. He was one of the first individuals considered a potential father, but a DNA test conducted shortly after Caylee's birth in August 2005 definitively excluded him. Despite this, the possibility of him being the father was a part of the early media narrative before the DNA evidence was widely known.

Jesus Ortiz: The Deceased Boyfriend

Another name that surfaced in connection with Caylee's paternity was Jesus Ortiz. Ortiz was a young man who had dated Casey Anthony. He was publicly named as a possible father, which reportedly stunned his own family. Tragically, Jesus Ortiz died in a car crash in 2007, before the full extent of the case unfolded. The speculation around him, like others, was never confirmed.

Michael Patrick Duggan: The Mother's Claim

In 2011, a woman named Donna MacLean came forward, claiming that her son, Michael Patrick Duggan, was Caylee's biological father. MacLean stated that her son, who had also died in a car crash, had confided in her that he had fathered a child with a woman named Casey in Florida. This claim, while compelling, was never substantiated with DNA evidence, leaving Michael Patrick Duggan's connection to the case unverified.

"Josh from Georgia": The Co-worker's Account

A former co-worker of Casey Anthony, Melina Calabrese, testified that Casey had told her Caylee's father was a man named "Josh from Georgia." According to Casey's account to her co-worker, the relationship was brief and one-sided. However, like the other names, this "Josh" was never located or confirmed to be the father. The shifting stories about the father's identity were a key component of the prosecution's argument about Casey Anthony's dishonesty.

The Enduring Accusation: Casey's Blame on George Anthony

The trial and the years following have been dominated not by the search for the biological father, but by Casey Anthony’s shocking accusations against her own father, George Anthony. During her defense in the 2011 trial, Casey's legal team presented a controversial theory that Caylee had died in an accidental drowning in the family swimming pool. The defense alleged that George Anthony, Caylee's grandfather, covered up the death to protect his daughter, Casey. This accusation became a central, though unproven, element of the defense's strategy. In depositions and subsequent interviews, Casey Anthony went further, directly accusing George Anthony of molesting her and being responsible for Caylee's death, claiming he drowned her granddaughter. George Anthony has repeatedly and vehemently denied these allegations, calling them lies designed to deflect blame. The defense's narrative, while failing to secure a conviction on the major charges, successfully sowed enough reasonable doubt in the minds of the jury regarding the prosecution's circumstantial evidence.

Latest Developments in 2025: The Case Continues to Resurface

Despite the high-profile acquittal and the passage of years, the Caylee Anthony case continues to generate new media attention and updates, especially in 2025. One of the most recent developments involves George Anthony, who participated in a new A&E docu-series. In this series, he reportedly took a lie detector test related to the circumstances of Caylee's death. The results and implications of this test have once again thrust the grandfather's role and his relationship with his daughter back into the public discourse. Furthermore, Casey Anthony herself has re-entered the public sphere. In March 2025, she reportedly joined the social media platform TikTok, stating her intent to use the platform to "advocate" for her late daughter. This move has been met with significant controversy, reigniting the public's fascination and outrage over the case. The constant resurfacing of the key players ensures that the mystery of Caylee's death, and the identity of her father, remains a current topic of discussion. The legislative impact of the case, known as Caylee's Law, continues to be a relevant entity. This law, enacted in several states, makes it a felony for a parent or legal guardian to fail to report a child's disappearance in a timely manner, a direct response to the 31-day delay in reporting Caylee missing. The ultimate truth about Caylee Anthony's biological father remains a secret held only by Casey Anthony. The numerous false leads, the tragic deaths of potential candidates, and the mother's shifting stories have ensured that this piece of the puzzle is likely to remain unsolved. The focus has long since shifted from paternity to the circumstances of the child's death, a debate that continues to be fueled by new media and the ongoing, painful public scrutiny of the Anthony family.
