Forensic examiner Stephen Marx said screenshots automatically archived by the device showed Dr. Conrad Murray was perusing emails the morning of June 25, 2009, including three letters referencing Omar Arnold –- a pseudonym Jackson sometimes used.

The emails sent to Murray by a staffer at his Las Vegas practice were briefly displayed for jurors and included copies of handwritten treatment records for “Arnold” dating back to 2006.

Conrad Murray witnesses: Who's who

One entry for November 2008 indicated the patient was being treated for “insomnia/anxiety” and listed Murray as his primary physician.

Another document Murray reviewed was entitled “Omar Arnold Medication Log.” It listed Benoquin, vitamins, Xanax and Valium, but made no mention of propofol, the anesthetic Murray was using as a sleep aid for Jackson.

A lawyer for the promoter managing Jackson’s comeback has previously testified that Murray was supposed to be collecting the singer’s medical records for the company insuring his comeback attempt.

The emails displayed in court indicate Murray’s staff was confused about his use of pseudonyms. In one record, the name “Mike Smythe” was crossed out and replaced with “Omar Arnold.” In another email, a medical assistant, Consuelo Ng, asked her boss, “Is Paul Farance him too?”

Jackson had used “Paul Farance” to get medical treatment, according to a search warrant filed in the investigation into Jackson’s death.

Murray faces a maximum of four years in prison if convicted of involuntary manslaughter.
