Suicide Agents Arrested

Four agents, all above 60 years old, from the "Final Exit Network" were charged in for assisting the suicide of a 58 year old man from Georgia.
The investigation began after the deceased man's family reported suspicious bustle in his death.
As part of the investigation, the investigators set up a undercover operation.

A detective becomes a member in "Final Exit Network" after paying $50 for the membership, to obtain their assistance with his suicide.
An "Exit Guide" was assigned to detective's case. The exit guide visited detective and instructed to purchase some items.
On the main day (February 25, 2009), the detective was visited by a "Senior Exit Guide" along with "Exit Guide".
The senior exit guide instructed the process and said after the member's death, all evidence will be removed from the scene.

Following this, investigators arrested Claire Blehr (76) of Atlanta, Thomas E. Goodwin (63) of Kennesaw & Dr. Lawrence D. Egbert (81) of Baltimore.
Nicholas Alec Sheridan (60) of Baltimore has been charged but not in custody. Investigators said more arrests could be made.

I've heard about lot of jobs but I wonder why they picked this "Hell Job" after their retirement.
