MICHAEL JACKSON's parents were fuming after DR. CONRAD MURRAY pleaded not= guilty to an involuntary manslaughter charge on Monday (08Feb10) - insis= ting their son's former doctor should have accepted responsibility for "k= illing" the singer.
Dr. Conrad Murray walked free

from court in Los Angeles after posting $= 75,000 (=C2=A347,000) bail, prompting the singer's elderly parents, Kathe= rine and Joe, to speak out against the physician.
Katherine ranted to reporters, "He's a monster... He should have pleade= d guilty. He killed my son." Meanwhile Joe told E! Online, "I didn't like today's hearing at all. I = just want justice done and that was not justice." Murray, who has denied any wrongdoing, surrendered to face allegations = of administering a lethal dose of the hospital anaesthetic Propofol to th= e late singer - but he did not come face-to-face with any member of the J= ackson clan.
The Thriller legend's sister La Toya, who was also present at the heari= ng, has vowed to "fight" until those responsible for the singer's death a= re brought to justice.
She says, "Michael was murdered and although he died at the hands of Dr= .. Conrad Murray, I believe Dr. Murray was a part of a much larger plan.
"There are other individuals involved and I will not rest and I will co= ntinue to fight until all of the proper individuals are brought forth and= justice is served."
