Robert Yancy, 39, was found dead in California on Monday (14.08.17) and his aunts, Timolin and Casey Cole, said the loss of his mother in 2015 was tough on him but he had been getting his life back on track.
They told PEOPLE: "We are at a loss for words."
Timonlin added: "He was deeply saddened over the loss of his mother.
"When Natalie died, he lost the most important person in his life. It was very hard for him."
And Casey said: "He bought a new place to live and was super excited about celebrating his 40th birthday on October 14. He didn't go to the doctor much, but he was feeling good. He was so busy with his life that he neglected that part."
The 56-year-old twins believe that their nephew suffered a "cardiac arrest" but they won't know for sure until after the release of the autopsy and toxicology reports.
Robert's father, producer Marvin Yancy, passed away following a heart attack in 1985 at the age of 34.
Timonlin added: "His dad died early, too, but Natalie never mentioned concerns over her son's health. The only comfort we feel now is that Robert is with his mother."
