A man, 24-year-old Dominick Rodrico, has been charged with the murder of 21-year-old Arianna Bailey Jones. After they met through social media, their first date took a tragic turn, ending with Jones’ remains found in a shallow grave in the Arizona desert, according to Arizona State Police.
Glendale police reported Rodrico’s arrest on Monday, revealing they had identified what they suspect are Jones’ remains in a remote area north of Phoenix.
Rodrico now faces a charge of first-degree premeditated murder, as per Fox 10 Phoenix.
In a post announcing the arrest, Glendale police extended their sympathies to the family of Jones, expressing a desire for “different kinds of closure” prior to the arrest.
Authorities believe that Jones and Rodrico met online and communicated before deciding to meet face-to-face. Their outing reportedly included a movie date before heading into the desert, where the incident is thought to have occurred.
Upon being interrogated, Rodrico denied any involvement in Jones’ death, alleging that two men attacked them during their time in the desert. “He said they were in this remote area and then out of nowhere, they were assaulted,” explained Jose Santiago, a spokesman for the Glendale police. “At some stage, he alleges he fled, leaving Mr. Jones behind.”
However, police noted that a variety of evidence—including physical, surveillance, and digital clues—pointed to Rodrico’s responsibility for the crime.
Detectives indicated they had enough evidence to justify his arrest, adding that Rodrico’s story changed multiple times during the interview process.
“His account kept evolving,” Santiago mentioned, “with some aspects sounding more dramatic at times and less so at others.”
Moreover, investigators found it peculiar that Rodrico didn’t report the supposed attack or contact law enforcement. “He failed to inform authorities about the incident,” Santiago added.
Rodrico reportedly suggested that after the incident, Jones was “probably not alive,” yet never reached out to report what he claimed happened. Surveillance footage also captured him cleaning the back seat of Jones’ car following her disappearance.
Moreover, police observed that Rodrico had injuries consistent with stab wounds, which he attributed to his supposed attacker. The department’s Real-Time Crime Center, along with surveillance and cellphone data, played crucial roles in reconstructing the couple’s movements.
Officers tracked the pair from Jones’ home to the theater and subsequently to the desert. A movie theater cup collected from the crime scene was instrumental in linking the burial site to their date.
Investigations revealed that Rodrico had taken Jones to secluded spots on previous occasions, but whether the murder was premeditated remains unclear. Santiago remarked, “It’s hard to say if this was planned or purely coincidental.”
Jones’ family reported her missing on July 7, having lost contact with her for several days. Family members mentioned they regularly communicated and found it unusual that they hadn’t heard from her.
Upon executing a search warrant at Jones’ residence, police noticed signs that suggested something was amiss. They discovered her cellphone left behind and her dog locked in a crate, apparently neglected for days.
“There were enough indicators that something suspicious was happening,” Santiago shared.
Detectives eventually located what they described as a shallow grave in the desert, with the coroner’s office working to ascertain the cause and manner of death. However, clothes and other physical evidence found at the grave matched those belonging to Jones, which facilitated identification.
In just four days, the case was wrapped up, aided by the department’s Special Investigations Unit, U.S. Marshals Task Force, and advanced technology. Santiago noted, “We tracked his movement to her apartment and other locations, including their outings to the movies and monitored their cellphone usage.”
Rodrico has a criminal history related to theft, was on probation at the time of his arrest, and faces a bail set at $2 million.
This murder charge comes less than a year after he was convicted for robbing two KwikTrip gas stations. Reportedly, he posed as an employee at a QuikTrip on Peoria Street, stealing around $200, and faced another arrest in May 2025 for a similar incident.
He eventually pled guilty to identity theft, receiving two years of supervised probation.
Investigators are still awaiting more forensic tests and coroner findings to uncover the motive behind this tragic incident.
