Re-posting one of my previous comments:
As an HR Manager who has written (many) policy manuals, I can address the termination aspect......
Most employers have a statement regarding "Employment at Will". The statement generally says something like:
"[Company] has the right to terminate any employee for any reason....."
Employers also have statements identifying conduct that may result in immediate termination. Such as: "In cases of serious misconduct, an employee is likely to be terminated immediately." The list may include several things (dishonesty, theft, harassment, aggressive behavior, etc.), but almost always includes "
any action that violates federal, state or local law."
IMO, I believe disposing of human remains on company property (for which he has been charged with murdering- gosh I hate typing that

), would fall into this category.
In addition; if the company has a policy stating that dating/having intimate relationships with a co-worker is forbidden, termination could occur at time of discovery. I'm just gonna go out on a limb here and say if LE had asked for CW's company phone and e-mail records, his intimate relationship was known to the company. Especially if the co-worker had admitted to this relationship prior to his actual arrest.
