Clinical depression may be at the heart of a suicide attempt by broadcaster Larry King's wife, Shawn King, 50, according to a police report posted at TMZ.com.

The Provo, Utah, Police Department report by Officer Martin Webb stated that empty pill bottles for Compro, Prometrium, [C]lonazepam, Ambien, Klonopin, Subutex, Cymbalta and Lyrica were on the bed and in her purse and in the bathroom, along with a letter that "led me to believe that [King] had intentionally taken the quantity of pills." Five handwritten pages were entered into evidence.

Cymbalta is the brand name of duloxetine, used to treat major depressive disorder, also called clinical depression. Klonopin is the brand name for clonazepam, and Lyrica the brand name for pregabalin, the uses of both of which include treating anxiety. Subutex is one of several brands of buprenorphine, which is used for opioid addiction in high dosages and moderate pain in low dosages. Prometrium is a brand of progesterone, used in hormone replacement therapy. And Ambien is a brand of the insomnia medication zolpidem. However, Compro, the brand name for prochlorperazine, is a tranquilizer taken in suppository form.

Sources told TMZ that King's depression has lasted more than five years, triggered by her husband's alleged involvement with her sister, Shannon Engemann. Engemann has denied any affair.

The police report said a witness stated King "is always depressed, but she had not mentioned anything that she would want to hurt herself or take her own life."

Larry King, 76, said in a statement, "I am extremely supportive of Shawn. Reports that we have fought are absolutely false. I love her dearly."
