                            'Injustice with Nancy Grace' explores the mysterious death of Michelle Mockbee and the story of the man in jail for her murder

What would you do if you knew it was your last day at work? Michelle Mockbee certainly had no time to think about it.

Michelle was murdered in the early morning of May 29, 2012, at Thermo Fisher Scientific in an industrial park near Florence. Mockbee had worked at the company for 16 years. She was the head of Human Resources and was married to Dan Mockbee, who also worked at Thermo Fisher Scientific. They had two beautiful children and were happy. But on that fateful day, she went to work a little early and never returned.

Michelle was beaten and her tied-up body was found by the operations manager at the company. She had also been gagged. There was a trail of blood leading out of her office to the scene. Her hands were tied behind her back according to the employee, who had described the scene to the North Kentucky Tribune at the time.

Because the facility itself had such high-level security, the police's first line of suspects were people who were in the Park when she was murdered. They zeroed in on 13 people — with one among them being her husband. Friends and family, however, maintained that Dan could not have been the person who killed Michelle because of how much he loved her and their kids — who were in first and fourth grades at the time. However, it was $700,000 in life insurance he had received that made him a suspect.

Police looked for clues like torn clothes or blood but couldn't find any. However, there was something odd about janitor supervisor David Dooley. He didn't have blood or torn clothes, instead, for someone whose job may get them dirty, he was exceptionally clean. Spotless white shoes. A witness had also seen them together that morning.

However, there was no smoking gun — not even physical evidence tying him to the murder. In fact, it was inconsistencies in his story that made him such a strong suspect. There was no murder weapon found and no concrete motive. 

The police believed he had broken into her office that morning, following which he had killed her. A colleague also testified that around the time that Michelle was killed, Dooley had gone home saying he had ripped his pants.

Dooley would eventually be convicted for killing Mockbee in October 2014. Dooley was found guilty of murder and tampering with evidence. The jury recommended life in prison, but that was later overturned after Dooley's defense team said they had not been given surveillance video evidence. An unidentified person had reportedly been seen on footage trying to break into the facility. This was 10 hours before her death. Dooley was, however, convicted in the second trial and sentenced to 43 years in prison in March 2019.
