Alberto's Alverez wife Anna told RadarOnline.com outside the couple's modest home in Pomona, Calif., on Thursday night that her husband is distraught over Michael's Jackson's death - and over the fact that he was inside the mansion at the time of the fatal emergency.
Alberto is the Jackson security guard who phoned 911 while Dr. Conrad Murray gave the singer CPR. He could be a key witness in the investigation into Jackson's death.
"My husband is very upset and he needs some time. He won't be home for a while," Anna told RadarOnline.com, adding that Alberto was staying at an undisclosed location. It is unclear why he is not staying at home and if police have told him not to talk to anyone.
Anna Alverez wouldn't tell reporters what her husband told LAPD and she refused to discuss what he told her about his 911 call seeking help for the stricken pop star.
Alberto's sister Monica also arrived at the home Thursday to assist Anna.
