Los Angeles (CNN) -- AEG LIve's lawyer asked a jury to find Michael Jackson responsible for his death, not the concert promoter. Attorney Marvin Putnam spent four hours Wednesday deliver his closing arguments in the trial of the wrongful death lawsuit brought by Jackson's mother and three children. "Plaintiffs want you to hold a concert promoter liable for Michael Jackson's overdose in his bedroom at night, behind locked doors on June 25, 2009," Putnam told jurors. "An overdose of the drug administered to Mr. Jackson by his longtime doctor -- Dr. Murray -- who he'd been seeing for years, a doctor he brought to Los Angeles from Las Vegas."

There was no need to check @placeholder's background because he was a licensed, successful doctor who was known to Jackson, Putnam said.
"All @placeholder knew was Dr. Murray was Mr. Jackson's longtime doctor."
