James Ransone’s cause of death has been confirmed days after the actor died at 46.

Ransone died by suicide, according to a Dec. 29 death certificate obtained by PEOPLE on Wednesday, Jan. 7. The late actor died on Dec. 19 in Los Angeles. The Los Angeles County Medical Examiner first ruled his death an apparent suicide.

Two days after Ransone’s death, his wife Jamie posted an Instagram, telling her late husband: “I told you I have loved you 1000 times before and I know I will love you again. You told me — I need to be more like you and you need to be more like me — and you were so right.”

“Thank you for giving me the greatest gifts — you, Jack and Violet. We are forever,” she added, referring to the couple’s two children.

A GoFundMe page was set up to help the family with expenses following the actor’s death, and the fundraiser’s description remembered Ransone as a “beloved husband, father, and friend.”

“James, who his friends called PJ, was funny, magnetic, brilliant, and endlessly alive. Above all else, he was an extraordinary father,” a message on the page added.

The tribute continued, “His wife, Jamie, known by her friends as Skipper, and their children, Jack and Violet, were the center of his world. They loved him infinitely, and he loved them just as fiercely in return. Their bond was deep, joyful, and unmistakable to anyone who witnessed it.”
