La Toya Jackson is struggling to hear “the lies and cover ups” in the trial against Dr. Conrad Murray.

Michael Jackson died of acute Propofol intoxication on June 25 2009 and his personal physician Murray has been charged with his involuntary manslaughter. He is currently on trial in Los Angeles and has denied the allegations.

Michael’s sister La Toya vented her frustration from the courthouse yesterday with a series of extraordinary posts on her Twitter page.

"Just arrived at court. Another day of sadness," La Toya Jackson tweeted Wednesday morning.

After the court was adjourned, La Toya expressed her annoyance at the day’s proceedings.

“@CNN @hlntv Court is over 4 2day I can't wait until justice is served! It's so hard 2 sit in the courtroom & hear all the lies & cover ups (sic),” she wrote on the social networking site.

Earlier in the day, La Toya revealed she was struggling to hear the evidence surrounding her brother’s death.

“It's so excruciating to relive the moments when Mike pasted. It's even hard to pretend to be strong for my mother. @CNN @hlntv #Murraytrial,” she wrote.

The star arrived in court carrying a sunflower - which was Michael's favourite flower - and sent a torrent of tweets criticising the evidence that was being presented.

In one sensational post earlier this week, La Toya claimed that Michael had been murdered. The 55-year-old also suggested that there are other witnesses who have yet to come forward to police.

“There are wives, girlfriends and employees who know exactly what happened to Michael, please come forward and tell what really happened (sic),” she wrote on Tuesday, before claiming,

“This is DEFINITELY A STRAIGHT MURDER TRIAL!!!! This is all a BIG CONSPIRACY and the doctor knows what happened (sic).”

Meanwhile, the court heard yesterday that Michael’s children were in tears when their father was found unresponsive.

Michael’s head of security, Faheem Muhammed, told the Los Angeles Superior Court that Prince Michael, 12 at the time, and Paris, then 11, stood in the doorway of their father’s bedroom crying as their dad’s physician tried to resuscitate him.

The trial is ongoing and is expected to last between five and six weeks.
