Brittany Murphy's late husband may have drained her finances

Murphy's former business manager is claiming that her late husband withdrew hundreds of thousands of dollars before his death in May

The controversy surrounding the death of Brittany Murphy has taken a grim turn with an allegation by Murphy's former business manager that her late husband, Simon Monjack, may have drained Murphy's savings by 80 percent before his own death in May.

People.com spoke with Jeffery Morgenroth, Murphy's former business manager, who added that the withdrawals have left Sharon Murphy, Brittany's mother, financially insecure.

"There were huge amounts of money in (Brittany's) pension plan and bank account, and all of that's gone," Morgenroth told People.com. "There was money being withdrawn by Simon, hundreds of thousands."

Linda Monjack, Simon's mother, denied that her son would have taken money. "If there is money missing, I have no idea where it is," she told People.

Sharon Murphy, who lived with her daughter and son-in-law, is, according to Morgenroth, having a hard time believing allegations that Monjack could have drained Murphy's accounts.

"She'll say, ‘I can't talk about that now," Morgenroth said. "She needs guidance on how to deal with things."
