On the one-year anniversary of Michael Jackson's death, Janet, Randy, Tito and Jermaine Jackson gathered at Forest Lawn Cemetery in Glendale, Calif. to pay their respects.
The group -- all dressed in black -- arrived around 11 a.m. PT and entered through a back entrance of the mausoleum in which Michael is interned. About 500 fans also quietly gathered, many wearing sequined jackets or white gloves, according to a witness.

Michael's children Prince, 13, Paris, 12, and Blanket, 8, were not in attendance. They were last publicly spotted in Hawaii Thursday with their grandmother (and legal guardian), Katherine Jackson.
"Sorry Big Bro, for not getting ur children there on the anniversary of ur last day. I tried," Twittered Randy.

Joe Jackson filed a wrongful death suit against Michael's doctor, Conrad Murray, Friday at the federal court in downtown Los Angeles, TMZ.com reported. Joe claims Dr. Murray withheld information from doctors and EMTs that could have saved Michael's life, and he's suing the doctor for unspecified damages as a result. (A federal court clerk told the site there was a "mistake" in the paperwork, though, so the lawsuit will have to be refiled.)
