His statement comes amid a report from police that his wife, Shawn Southwick King, was found unconscious two weeks ago in a Provo, Utah, home, with empty pill bottles strewn on her bed in a possible suicide attempt.
Southwick, 50, who has a history of painkiller addiction, was recently involved in divorce proceedings with King, 67, but they reconciled a week later. She was discovered May 28 by her father, Karl Engemann, who dialed 911.
"I slap her and I holler at her and she opens her eyes half way and puts them back down again," Engemann tells the emergency operator.
Police arrived to find notes that indicated Southwick "might hurt herself, such as that she wished to be buried in Utah," according to an officer's report.
"Wording on the letter led me to believe that [Southwick] had intentionally taken the quantity of pills," the report says, adding Southwick's father told investigators that Southwick is "always depressed, but she had not mentioned ... that she would want to hurt herself or take her own life."
Bottles for prescription medication Compro, Prometrium, Clonazepam, Ambien, Klonopin, Subutex, Cymbala and Lyrica were found on her bed, purse, and in the bathroom, with many of the pill bottles empty, the police report reads.
According to the police report, Southwick was last listed in critical condition at a local hospital, although her current condition is unknown. In June 2008, she sought treatment for addiction to painkillers, which her father said was in part due to her longtime struggle with migraines.
"I am extremely supportive of Shawn," Larry King said in his statement. "Reports that we have fought are absolutely false. I love her dearly. Our marriage is still together and I am staying very close to our children, who we love immensely. We shall go through this difficult time intact as a family."
Calls to Southwick's family weren't immediately returned.
