The suspected Florida mail bomber is a lost and “sick individual’ who estranged himself from his family but eventually “found a father” in President Trump, his family’s lawyer said.

Cesar Sayoc Jr. — who is accused of sending a slew of packages containing explosive devices to high-profile liberals — was abandoned by his father as a child and “has told his mother that he hates her,” Miami lawyer Ronald Lowy said.

“This was someone lost, he was looking for anything and he found a father in Trump,” Lowy added to CNN.

Though Sayoc’s dad is Filipino and his mom is Italian, the steroid-abusing bodybuilder claimed to be of Native American descent because he was trying to create an identity — which he found by becoming obsessed with Trump, Lowy said.

“He doesn’t seem to recognize reality. He lives in a fantasy world,” Lowy said to local outlets. “The signs of mental illness are clearly there.”

Lowy, who has represented Sayoc in four prior criminal cases, said the suspected mail bomber had “trouble articulating concepts” and “doesn’t live life in a normal way.”

“You talk to him and he speaks like a 15-year-old, like a child,” Lowy added. “This seems like such a sophisticated crime, I have trouble believing he had the mental capacity to create operating bombs.”

Sayoc’s mom found out her son had been arrested when she woke up from surgery Friday, Lowy said.

“My heart goes out to these people because you couldn’t imagine a more decent and loving family. They did everything they could,” he said.
