Experts Testify on Phone Data and DNA in Chad Daybell Trial

The Chad Daybell trial resumed today with critical testimonies from forensic experts, shedding light on the digital and DNA evidence crucial to the case. Patrick Eller, CEO of Metadata Forensics, continued his testimony, offering detailed insights into the phone data analysis that forms a pivotal part of the investigation.  

Eller, a digital forensic examiner with extensive experience, testified about the search and analysis of phone data related to Chad Daybell and Alex Cox. Eller revealed that despite efforts, no location data for Chad Daybell's phones were found at the Daybell property during the crucial dates under investigation. "Chad had multiple phones," Eller noted, emphasizing the complexity of tracking his movements accurately. 

Eller discussed the process of geofencing and metadata analysis, explaining how Google’s data helped identify devices near the Daybell property. "The best source of data about phones is the phone itself. Even with settings toggled, the data can still be found on the device," Eller stated. He clarified the difference between visible data and the metadata attached to it, using a digital image analogy to illustrate his point.

During cross-examination, prosecutor Rob Wood focused on the phone records and geofence data. Wood presented a map with data points showing phone activities near the Daybell property. Eller confirmed seeing Chad Daybell’s phone number calling Alex Cox on September 9, 2019, around 8 a.m. However, Eller admitted he couldn't recall if he examined Tammy Daybell's phone, adding a layer of ambiguity to the investigation.

Defense attorney John Prior's redirect examination sought to clarify whether there were any data points indicating that Chad Daybell and Alex Cox's devices were together at the property. Eller confirmed there were no such data points, reinforcing the defense's narrative.

The afternoon session featured Dr. Greg Hampikian, a professor from Boise State University and an expert in biology and criminal justice, who continued his testimony regarding DNA evidence. Hampikian’s review of DNA data found no evidence that Chad Daybell’s hair was on the tape used to bind JJ Vallow’s body. "The four hairs tested did not belong to JJ Vallow, Lori Vallow, Chad Daybell, or Alex Cox," Hampikian testified.   

Hampikian also discussed his involvement in other high-profile cases, including the Amanda Knox case, to underscore his expertise. His lab, while not accredited like a criminal investigatory lab, provides crucial analysis using advanced tools and technology.

The testimonies of Patrick Eller and Dr. Greg Hampikian provided significant insights into the forensic analysis central to the Chad Daybell trial. Eller's expertise in digital forensics and Hampikian’s DNA analysis are critical as the court continues to dissect the evidence. The trial remains a focal point of public interest, with each session revealing more about the intricate details of this high-profile case.

This case continues to evolve as the court delves deeper into the digital and biological evidence, seeking justice for JJ Vallow and Tylee Ryan.
