The 27-year-old girlfriend of Michael Jackson’s personal physician will testify before a California grand jury this week.

The LA County District Attorney’s office have targeted Dr. Conrad Murray, 56, the last person to see Jackson alive before he suffered a cardiac arrest on June 25th.

Nicole Alvarez, who has a baby by Jackson’s former cardiologist will be asked to give testimony, but the grand jury will not determined if Murray should be charged with a crime “at this time.”

This Summer, prosecutors searched the apartment where Alvarez lives with the couple’s infant son, but she was not forthcoming with detectives, according to the LA Times.

Dr. Murray is still married to his wife, Blanche, and has fathered six children with different women.
