Jackson's father files wrongful death lawsuit

The father of Michael Jackson has filed a wrongful death lawsuit against Dr. Conrad Murray.

The doctor is accused of giving the late pop star a powerful drug and being slow to call for medical help.

The lawsuit, which had been expected, was filed on the first anniversary of Jackson's death, just beating a one-year deadline for an action against the "Thriller" singer's doctor.

Joseph Jackson, 80, alleges that Murray was too slow to call the emergency medical services for help and he later made statements to authorities which turned out to be false, including that Murray was by Jackson's side monitoring his pulse.

In a statement, Murray's lawyer said, "We continue to maintain Dr. Murray neither prescribed or administered anything that should have killed Michael Jackson...Dr. Murray has not been found guilty of anything and we believe his innocence will be proven in a court of law."

Authorities have ruled Jackson's death a homicide and said propofol was the key drug in Jackson's system that led to his death at age 50 on June 25, 2009, in Los Angeles.
