Mariah Carey hadn't seen her sister Alison for decades before her death, according to a friend of Alison.
David Baker, a friend of Carey's sister for nine years, claimed Alison hadn't seen the "We Belong Together" singer since either 1994 or 2002, People magazine reported.
Carey wrote in her 2020 memoir that it was "emotionally and physically safer" not to have contact with her sister or brother.
"Alison was a highly intelligent, very sensitive person," Baker told the outlet.

Baker met Alison in 2015 after she suffered a brain injury during a home invasion.
"I saw somebody who needed help, and I knew I could do it," he told People magazine. "She’d tell me that she was so glad I was around.
"More recently, before she got sick, if I went somewhere for an hour, she’d call and say, ‘When are you coming back?’ And I’d say, ‘Well, I’ll be there in 20 minutes,'" he recalled. "And then she’d call a second time and say, ‘When are you coming back?’ Because short-term memory was affected by the brain injury."

Alison and her mother didn't have the best relationship. Carey's estranged sister sued their mother in 2020, claiming she was forced to endure sexual abuse from multiple men at Satanic worship meetings when she was 10 years old.
In a lawsuit obtained by Fox News Digital, Alison accused Patricia of allowing and encouraging an undisclosed number of men to engage in sexual acts such as forcible touching and made her witness people engaged in sexual acts with adults and children.
She also claimed it took place at "middle-of-the-night satanic worship meetings that included ritual sacrifices."
