Why Rick Matros isn't in prison for negligent homicide?

I witnessed Rick Matros, former CEO of Sun Healthcare, now CEO of Sabra REIT, Sabra Films, et al, neglect patients in his Sunbridge Newport Beach skilled nursing home in 2002-2003 to the degree five patients died so why isn't he in prison?  Stella Carter, Richard Laga, Evelyn Calvert, my late mother, Betty Harness and the  man in Room 2-B October, 2003 all died from either fecal impaction (no excuse), gangrene, not following Physician's orders for saline I.V. "stat" -Stella Carter, and in my late mother's case, MSRA without ventilation to patient's rooms in the form of a working HVAC for which they had an injunction from the State of California not to repeat this slumlord condition as he did in 2001 which killed numerous patients in his Burlingame facility in Northern California.

There is no excuse for the lack caring by Richard K. Matros as the CEO when warned by patient's families to help them. 

There is clear fraud as the agency responsible for the equipment in skilled nursing facilities, Statewide Office of .... had three field reports purged from their public files which I had given to my attorney in my wrongful death lawsuit, Daniel Leipold, and recovered when I sued him for malpractice.  Leipold threatened me in mediation for Mr. Matros, saying I'd be harmed if I pursued my case and wasn't getting the keys to Matros' Bentley.  Mr. Leipold died just two weeks after learning I'd retained the law firm of Andres & Andres to sue for this malpractice.

Even Dr. L. Scott Stoney warned me that Matros would plant drugs or a gun in my car if I didn't back off.  I have no fear -bring it on.  Judge Gregory Jones told me I proved Matros killed my mother, certainly I could state it, freedom of speech, protected speech and peaceful protest, when I made posters that read:

HERE HE LIVES WITH A VIEW OF THE SEA
SLUMLORD FOR THE ELDERLY
RICK MATROS
CEO OF SUN HEALTHCARE GROUP INC
CITED BY THE DEPT OF HEALTH FOR LACK OF STAFFING
CITED FOR NO HVAC SYSTEM TO PATIENT ROOMS
SHAME SHAME SHAME

Who doesn't believe he should be in prison?
