( CNN ) -- Opening statements in the Michael Jackson wrongful death trial will be heard Monday , April 29 , with the first testimony soon to follow , the judge announced Tuesday . Michael Jackson 's mother and three children are suing AEG Live , claiming the concert promoter was liable in the pop star 's June 25 , 2009 , death . Jury selection concluded Tuesday afternoon with selection of six alternates to back up the 12 jurors chosen Monday . Jackson Lawyer Brian Panish called it a `` good , diverse '' jury after the 12 main jurors were seated Monday . The main jury panel includes six men and six women , and there are four male and two females alternates . The trial , which could last three or four months , is expected to include testimony from Prince and Paris Jackson , the singer 's two oldest children , and a list of celebrity witnesses . Jackson died two weeks before his `` This Is It '' comeback concerts , organized by AEG Live , were to have debuted in London in summer 2009 . Lawyers for Jackson 's mother , Katherine ; and children , Prince , Paris and Blanket , argue that AEG Live is liable because the company hired and supervised Dr. Conrad Murray , who used a surgical anesthetic in a fatal effort to treat the singer 's insomnia as he prepared for the comeback concerts . Murray was convicted of involuntary manslaughter and is serving a prison sentence . AEG Live 's lawyers argue that Jackson chose and controlled Murray . The lawsuit seeks a judgment against AEG Live equal to the money Jackson would have earned over the course of his remaining lifetime if he had not died in 2009 . If AEG Live is found liable , it could cost the company several billion dollars , according to estimates of Jackson 's income potential . AEG Live is a subsidiary of AEG , a global entertainment company that was up for sale recently with an $ 8 billion asking price .
