"Dealing with her grief has become more difficult as the days go on, however, in large part because of the constant speculation and innuendo in the media. Newspapers, television and online media have fostered a poisonous atmosphere in which Leanna's every word, action and emotion -- or failure to cry in front of a crowd -- is scrutinized for some supposed hidden meaning."

'I miss him with all of my heart'

Leanna Harris told CNN at the beginning of the investigation that a lawyer had advised her not to speak to the media, so not much is known about her.

She did not testify at her husband's probable cause hearing, but arrived before the proceeding began and took a seat with family members, holding hands with the woman sitting next to her.

She did speak at her son's funeral. She told mourners in Tuscaloosa, Alabama, that before Cooper's birth, she was concerned "about never being able to have a child."

Leanna Harris described the toddler as perfect and told how he changed her and her husband's lives.

"As children do, he turned our lives upside-down," she said. "Cleaning, changing diapers, dinner, bath time. Finally, what I would call mommy time. I wouldn't trade it for the world."

Leanna Harris said Cooper had had trouble sleeping of late, and he had slept with her and her husband the two nights before he died, "snuggling in between both of us."

"I remember turning over in the middle of the night. His mouth was open and his full toddler lips just breathing right into my face. I will cherish that moment forever."

She said she was "happy" that Cooper would miss some of life's letdowns, including his first heartbreak, his parents' and grandparents' deaths and who to sit with at lunch at middle school.

"I miss him with all of my heart. Would I bring him back? No. To bring him back into this broken world would be selfish," she said.

The mother closed by saying that she wasn't angry with her husband and that Cooper "meant the world" to Ross, whom she described as a "wonderful daddy."
