In due course, Dateline aired the saga and depicted the timeline, the chief proof, and the suffering that was caused to Michelle's family and coworkers through the crime.


Dateline: Who is David Dooley?

David Dooley was a janitor at ThermoScientific, the same site where Michelle Mockbee was an employee. On that morning when the murder took place, the security camera at the warehouse recorded Dooley's coming and going, and so he was made the center of attention by the investigators.

Moreover, inconsistencies in his account of the events that day drew the attention of the police and, alongside some other circumstantial evidence, rendered him the prime suspect.

Although some reports refer to workplace misconduct, such as the claim that he had done time cards, court records do not point to this as a direct reason for the murder. It is argued by sources like Oxygen and The Cinemaholic that the payroll fraud allegations are strong enough, but do not clearly state that such fraud was the reason behind Michelle Mockbee’s death.


The investigation

Circumstantial evidence played a major role in the investigation of Michelle Mockbee's death. Thus, they made a timeline for the day of the crime on May 29, 2012, by examining the security cameras, interviewing the hotel staff, and checking different papers.

The investigators still regarded Dooley's identity, location, and remarks as doubly significant and at the same time very vital to the case, even though the murder weapon was still not located, and no forensic evidence pointed directly to Dooley.

There are also reports of pry marks being visible on the office door. A screwdriver found in Dooley’s locker matched the size of these marks, but this is considered circumstantial evidence, not the smoking gun. Dateline stresses that the investigation was very detailed, but it was mainly based on the suspect's behavior and on circumstantial evidence to develop the case.


Arrest and charges

The arrest of David Dooley occurred on the 27th of September, 2012, and he was charged with first-degree murder for the death of Michelle Mockbee. The prosecutors concentrated their evidence against Dooley through several suspicious behaviors he had, his statements, and the surveillance and other methods used in the investigation.


The trial and conviction

The Dooley trial took place in 2014. The prosecution insisted that his actions and being at the scene, plus circumstantial evidence, pointed him out as the murderer. The defense argued that the proof was not strong, like the unknown DNA on the corpse and the presence of other possible suspects. However, the jury convicted Dooley of first-degree murder.

The case was subsequently retried, and in 2019, Dooley's sentence was extended to 43 years, which also comprised the charges of tampering with evidence.


Technology in the investigation

The use of digital and surveillance technologies was crucial to this inquiry. The images recorded by the security cameras were used to prove that Dooley’s in certain places on the day of the murder and helped to build a timeline that the police later could use to evaluate his participation.

Although the case was devoid of direct physical evidence, modern detective methods were still very vital in the persuasion of the jury against him via circumstantial evidence.


Controversies and questions

Following Dooley’s conviction, the discussion regarding the quality of the evidence continued. Dateline showcases these controversies, which include discussions about circumstantial evidence and whether all avenues of investigation were entirely explored.

According to sources such as Oxygen, there were some in the audience, including experts, who dared to express doubt over whether every possible lead got the attention it needed. On the other hand, officials assure that the evidence corroborating Dooley's guilt was strong enough to bring about a conviction.
