Cathriona White's body was found by two friends on Monday (28Sep15) night and law enforcement sources told TMZ.com there was a suicide note, which mentioned Carrey, at the death scene.

A full autopsy has yet to be conducted, but Winter tells People magazine all the signs point to suicide.

He says, "She was pronounced dead at 8:40 pm at a residence.

"It was reported as a possible suicide. There evidently was a note found. There were pills located near her... but the final cause of death won't be released until we get full toxicology and tests back."

On Tuesday (29Sep15), Carrey paid tribute to his ex, stating he was "deeply saddened by the passing of my sweet Cathriona."

He added, "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."

Her family has also issued an emotional statement to the Irish Independent. It reads: "The family of Cathriona White sincerely regret the untimely passing of their beloved daughter and sister.

"Cathriona was a shining light in our lives who was loved deeply by her entire family. We will miss her terribly and at this difficult time we ask to be left in private to mourn our loss. There will be no further statements on behalf of the family."

The Irish-born make-up artist was 30. She and Carrey had been dating on and off since 2012.
