In an interview over the weekend with The Times of London, Rwaramba said she routinely had to pump out Jackson's stomach after he'd ingested too many drugs. The paper noted that Rwaramba and Jackson had a falling out.
"I had to pump his stomach many times. He always mixed so much of it," Rwaramba told the Times, referring to drugs. "There was one period that it was so bad that I didn't let the children see him. ... He always ate too little and mixed too much."
According to Rwaramba, Katherine Jackson told her, "Grace, the children are crying. They are asking about you. ... Where are you? Come. I will pick you up from the airport."
Mark Lester, the children's godfather, has said he would be willing to adopt the children but doubted the family would let him.
"If called to do so. Of course I would. Michael has a large family. I'm sure the children will be well looked after. ... This is early days here. I extend my arms out to them, but they're American kids and I'm sure the family network will have put something in place," said Lester, who is British.
"The kids were everything to Michael. They were his whole life," Lester added.
Workers from the Los Angeles County coroner's office returned to Michael Jackson's home Monday afternoon, retrieving medication and other evidence for their investigation of how the pop star died.
Ed Winter, the assistant chief county coroner, said that based on information obtained by the Los Angeles Police Department, his office had more questions about the medications in Jackson's home.
The investigation will continue for four to five weeks and will include extensive testing, he said.
"The family has been extremely cooperative," he said.
Members of the Jackson family have expressed doubts about the coroner's investigation, and Monday Joe Jackson said he would wait for private autopsy results before burying his son.
"We're not ready for that," he told the press about a funeral. "We don't have the time frame for that. ... We want to see how the second autopsy comes out."
On Monday, the promoter that runs the London arena where Jackson was scheduled to perform 50 concerts announced that it would offer full refunds to people who bought tickets to the shows.
AEG Live, the promoter, said that fans can also receive the concert tickets as souvenirs, but then they would not receive full refunds.
