Los Angeles (CNN) -- Tears flowed from Dr. Conrad Murray's eyes Wednesday as he listened to an elderly patient tell jurors that Murray had opened a clinic in the Acres Homes community of Houston in honor of his father, who had practiced there.





After 17 days of hearing about how pop star Michael Jackson died under Murray's care, jurors began hearing Wednesday from people who say the doctor saved lives.





Ruby Mosley was one of five character witnesses called by Murray's defense lawyers Wednesday morning as his involuntary manslaughter trial nears an end.





"If this man had been greedy, he never would have come to an area, a community of Acres Homes, 75% of them poor, on welfare and Social Security," Mosley said.





Murray continued to dab tears from his eyes even after Mosley left the stand.





"He's the best doctor I've ever been to," said Gerry Causey, a 68-year-old former patient of the man accused of causing Jackson's death."And I just don't think he did what he's being accused of," Causey added, under cross-examination by the prosecution.





Much of the prosecution's case has been spent trying to demonstrate that Murray gave reckless and incompetent medical treatment as Jackson's personal doctor in the last months of his life.





Causey met Murray 11 years ago when he was rushed to a Las Vegas hospital with a heart attack, but they became friends since then, he testified.





"It's because of Dr. Murray, the way he cares for you, the way he makes you feel," Causey said.





Prosecutors contend that Murray abandoned his patients in Las Vegas and Houston for the $150,000 a month Jackson had promised him.





"There's no way, he's not greedy," Causey said. "He doesn't charge me my deductable, never has."





Las Vegas heart patient Andrew Guest, who followed Causey on the witness stand Wednesday, said Murray "makes sure you're ok during the procedure."





"That man sitting there is the best doctor I've ever seen," Guest testified.





Murray treated Dennis Hix by putting 14 stints into arteries around his heart 11 years ago, Hix testified.





"I'm 66, I've gone to a lot of doctors, a lot of doctors and I've never had one that gave me the care that he did," Hix said.





Murray never charged Hix beyond what his insurance would pay, he said. "I had a type of insurance that don't hardly pay for nothing," he said. "So he did it for me free."





Two medical experts for the defense, including anesthesiologist Dr. Paul White, are expected to follow Thursday and possibly Friday. This would set the stage for closing arguments and jury deliberations early next week, although it's possible that could come Friday.





Jackson's sisters Janet and La Toya, as well as his brother Randy, were in court for Wednesday's testimony.





The promoter of Jackson's ill-fated "This Is It" tour testified Tuesday that Jackson's fear that producers would "pull the plug" on the shows if the singer missed more rehearsals was unfounded.





"No one on our end was ever contemplating pulling the plug," said Randy Phillips, the head of AEG Live.





Murray's lawyers contend Jackson self-administered the overdose of drugs that killed him in a "desperate desire to get to sleep," because he feared without rest he would miss his next rehearsal and trigger the cancellation of his comeback concerts.





If the tour was canceled, Jackson would have to pay for all of the production and rehearsal costs, Phillips said, although the judge would not let him tell jurors how much that might have been. Defense lawyer Ed Chernoff estimated the cost to be about $40 million, leaving him "a very, very poor man," but it was not while the jury was present.





Concert director Kenny Ortega sent Phillips an e-mail five days before Jackson's death, referring to Jackson's fear the
