“He really was a wonderful guy, but it’s hard to be in Texas when your dad’s Willie Nelson. You can’t get away from it,” said Paula, the singer’s daughter with third wifeConnie Koepke. “When Billy passed, it was terribly hard on him — on all of us. It was really hard for him because that was his first son.”

Billy was found dead at his log cabin home in Davidson County, Tennessee, and officials said he was legally drunk at the time of his death, which was around 2 a.m., according to a 1992 story published in PEOPLE.

Friend Buddy Frank had visited him just hours before, on Christmas Eve, and told PEOPLE that Billy — an occasional musician with plans to release an album of original gospel songs — had been forward-thinking, getting himself a haircut and buying new pants and boots.

In the docuseries, Billy’s sister Lana said her brother suffered from depression: “He didn’t want to be depressed, he didn’t want to be that guy. He tried really hard, he did.”

Sister Susie added that she and Billy were just 17 months apart, and were inseparable (Nelson shared Billy, Lana and Susie with his first wife Martha).

“We did everything together, but he had a lot of issues,” she said. “They became more and more.”

In the docuseries, Nelson talks about the loss only briefly, saying, “Those were bad times” when speaking about his busy 1992, which aside from the fallout of Billy’s death, also included struggles with the IRS and a grueling performance schedule.

In spite of the tragedy, Nelson’slate sister Bobbiefound a silver lining, saying in the docuseries that she and her brother “grew even closer” after Billy’s death.

“It’s not that we had long talks about our grief — that’s not Willie’s way,” she said. “We didn’t have to talk about it. We knew.”
