WASHINGTON (AP) — An American businessman detained for four months after the presumed death of his travelling companion in Aruba said Tuesday he had nothing to do with her disappearance.

Gary Giordano, 50, was released from jail Tuesday, and on Wednesday, an appeals court ruled that prosecutors lacked sufficient evidence to continue holding him in the disappearance of Robyn Gardner.

During an 11-minute interview Thursday on ABC’s “Good Morning America,” Giordano refused to detail what happened to Robyn Gardner on Aug. 2, the last day she was seen alive, saying he has told that story to investigators “50, 60 times.” He has said she was swept out to sea while snorkeling. Her body has not been found.

Giordano, of Gaithersburg, Md., tried to clarify aspects of his behaviour that investigators have called suspicious. He said the $1.5 million accidental death policy he took out on Gardner was part of a travel insurance package that covered both of them. He said he always takes out travel insurance because he wants his three sons to be protected if something happens to him.

“If I go travelling and I disappear, I want them to be covered. I maxed out on everything,” Giordano said.
