An eyewitness tells ET that Carrey met with officials at White's former residence hours later, and gathered up some of his late girlfriend's things. Carrey had security with him while going to the Sherman Oaks house -- where he stayed for three hours -- before going back to his own home with boxes of White's possessions.
Carrey has also been in touch with White's family since the shocking news. White's sister, Lisa White, was seen pulling away from Carrey's residence late Wednesday night in a black SUV, after spending about an hour and a half with the star.
The actor is "doing everything he can" to help and is also "helping out [the family] financially as well," People reports. "They are all just shocked," a source tells the magazine. "No one [from her family] is putting any blame on Jim."
"I am shocked and deeply saddened by the passing of my sweet Cathriona," Carrey said in a statement to ET. "She was a truly kind and delicate Irish flower, too sensitive for this soil, to whom loving and being loved was all that sparkled. My heart goes out to her family and friends and to everyone who loved and cared about her. We have all been hit with a lightning bolt."
Assistant Chief Coroner Ed Winter told ET that White had left a note for Carrey before her apparent suicide. "There were several pieces of paper, notes and envelopes found. One was addressed to Jim, but it was not signed or dated," Winter said.
Winter also disclosed she was found in her bedroom lying on her bed, and that there were prescription pill bottles found nearby.
