Westphal said that Garland, alone, “demanded” that Otash move in with her.

“Fred Otash moved in,” Westphal explained. “And when she did, she soon discovered his addiction to alcohol and drugs. So, she took charge of the situation. Much to Judy’s dismay, she flushed all the alcohol in her garage and flushed all her pills down the toilet. She struggled with the comeback.”

Westphal added, “He had to spend many sleepless nights.” “She pretty much demanded or forced Fred to stay with her every night until the wee hours of the morning. They would just sit in her living room, and he would patiently listen to her talk about all the trials and tribulations she went through was in his life. He knew it would be good for him to get it all out.”

According to the book, Otash described Garland as “a crazy mixed-up child inside a woman’s body, afraid to live, full of self-doubt, alcohol, and killing herself with those little pills.” Since Garland was heavily sedated, the book alleges that Otash was beholden to a nanny who looked after his three young children: Liza Minnelli, 12; Lorna Luft, 5; and Joey Luft, 3.

The book claims Otash found pills scattered throughout Garland’s home, including uppers, downers, and “some pills he did not recognize.”

According to the book, Otash later recalled: “One day, a very shy Liza, caught in that awkward stage between a little girl and a young woman, came out from behind the house where I was washing my car. Was, and he thanked me for helping his mother.”
