"Knowing what I know about Brian, he lied about everything," Brian Hooker's stepmother, Donna Hooker, says.
She discussed her stepson during a livestream appearance on the "Surviving the Survivor" investigating Lynette's disappearance.
Donna Hooker, who was married to Brian's father for more than 40 years, said she lived with her stepson during part of his teenage years in the 1980s.
She described him as intelligent, quiet and reserved. She said investigators in both the Bahamas and the United States have not reached out to her, but she is willing to answer any questions.
"He had his own room and everything, and he would stay in his room all the time," she said to the outlet. "He was quiet and, for a long time, he would just stay in his room and not do much of anything," she said.
She said, over the years, it became harder to get ahold of her stepson. She said she and Brian's late father, George, would try and reach out to him through his sister, Jennifer, who lives in California.
Donna Hooker told a journalist the last time she saw her stepson was in April 2022, when he visited his father after George Hooker suffered a stroke, and she has not heard from him since.
She said she learned of Lynette's disappearance from a family member in Texas who told her to turn on the news and that Jennifer never responded to multiple messages after reportedly traveling to the Bahamas following Brian's initial release from Bahamian custody.
The investigation into Lynette's disappearance is active and ongoing.
