In 2017, Moore-Martin suffered a seizure but was able to recover and help the police convict Field after giving interviews and sharing evidence. 

On May 11, 2017, Moore-Martin died of natural causes. 

What happened to Ben Fields?

The then-28-year-old was found guilty of murdering Farquhar on August 9, 2019, but was cleared of conspiring to kill Moore-Martin and of her attempted murder.

Field admitted that had poisoned Farquhar and that he "psychologically" manipulated both victims, however never admitted to his involvement in their deaths. 

Police evidence also suggests that Field has over 100 'clients' on a list similar to Farquhar and Moore-Martin, including his parents and grandparents. 

He was later sentenced to life in prison with a minimum sentence of 36 years.
