LOS ANGELES (CBSLA.com) — Joe Jackson, Michael Jackson’s father, has dropped a wrongful death lawsuit against Dr. Conrad Murray and Applied Pharmacy Services, according to court papers.

Jackson’s attorney, Maureen Jaroscak, filed a one-page request Monday with Los Angeles Superior Court Judge Yvette Palazuelos for dismissal of her client’s case.

Jackson said the Las Vegas pharmacy allegedly sold Murray propofol the month before his son died on June 25, 2009.

The lawsuit originally included AEG Live, the promoters of Michael Jackson’s planned 2009 comeback tour, as a defendant, but Jaroscak removed the company from the lawsuit six months ago.

Jackson alleged the company was negligent in hiring Murray as the late singer’s personal physician.

Murray was convicted Nov. 7 for involuntary manslaughter in Michael Jackson’s death and was sentenced to four years in prison.

Palazuelos is managing Katherine Jackson’s separate negligence case against AEG Live, which is set for trial April 2, 2013.

It is unclear whether a settlement was reached.
