Los Angeles (CNN) -- The co-author of a study on propofol addiction funded by AEG Live and used in their defense in the Michael Jackson wrongful death trial lost his medical license for writing illegal drug prescriptions, according to testimony. 

Dr. Torin Finver was hired to help with the AEG Live study after he lost his job at a pizza parlor and took a job driving a Goodwill truck, said Dr. Paul Earley, who testified Wednesday as an expert witness for the concert promoter. 

Finver was "destitute, dead broke, and I wanted to help him," Earley, himself a recovering heroin addict, testified. 

The revelation was a bizarre twist in the trial of the billion-dollar lawsuit filed by Jackson's mother and three children, which is being heard by a Los Angeles jury. The four-month-long trial is nearing a conclusion. 

AEG Live lawyers will announce if they have any more witnesses to call before playing the video depositions of three more doctors on Friday. Jackson lawyers would then take several days to call rebuttal witnesses before closing arguments are heard, which is likely to happened around September 23. 

Earley testified that he never disclosed to AEG Live lawyers that his co-author had lost his medical license. Ironically, the company is being accused of the negligent hiring of Dr. Conrad Murray, convicted in Jackson's death because it allegedly failed to check Murray's background before hiring him. 

Jackson lawyer Kevin Boyle also grilled Earley over his nondisclosure that he was working as a paid consultant in AEG Live's defense when he submitted the study for publication in a medical journal.  QUESTIONS:
