"People were worried about her," Baker said. "More than one person over the last couple years told me they were worried about her."
One person who was worried was former friend Jasmine Lennard, a model and British reality TV star. "I tried to get her off drugs and alcohol. I tried to get her into a 12-step program. I tried to help take care of her daughter and gave her money. I am the only person who helped this girl," Lennard told the New York Post's Page Six.
On Tuesday, Lennard said in a statement to ABCNews.com, "Casey was a classy, witty, beautiful lady, whom I loved deeply. My thoughts go out to her family, who have suffered such a terrible loss. I am completely devastated."
