Los Angeles (CNN) -- Jurors began deliberations Thursday in the Michael Jackson wrongful-death trial, potentially bringing the contentious case to a close after five months of testimony and three days of closing arguments. The 12 jurors spent two hours in the jury room Thursday afternoon before ending their day; they will return Friday morning for more deliberations. Katherine Jackson's lawyer delivered his final arguments in the AEG Live trial Thursday morning, delivering his rebuttal to defense closing arguments. AEG Live's Marvin Putnam had asked jurors to find Michael Jackson responsible for his death, not the company that promoted and produced his comeback concerts in 2009.

The Jacksons are asking for $1 billion to $2 billion in damages from AEG Live
Putnam argued that the number, if the jury finds @placeholder liable, should be closer to $21 million, the amount of money AEG Live's expert calculated Jackson would have given his mother and three children over the next 16 years.
