Jackson was acquitted on all charges after a trial.
LaParruque called Jackson "very down to earth," saying he was proud to have worked for him.
"There were times there were difficulties, but for the most part it was a pleasure working for him," he said.
He noted that one problem Jackson had was keeping up with his cell phones. He lost 27 of them, he said.
The wrongful death trial begins its 15th week in a Los Angeles courtroom Monday. The judge projected the trial will last until the middle of September.
