Morales, a sniper instructor in the early 1960s in secret camps where Cuban exiles and others trained to invade Cuba, realized in the hours after President John F. Kennedy was assassinated in Dallas in 1963 that the accused killer, Lee Harvey Oswald, had been one of his sniper trainees.

Morales also told his two sons that two days before the assassination, his CIA handler told him and his “clean-up” team to go to Dallas for a mission. But after the tragic events, they were ordered to go back to Miami without learning what the mission was about.

The claims made by Ricardo Morales Jr. during a show on Miami’s Actualidad Radio 1040 AM, add to one of the long-held theories about the JFK assassination — that Cuban exiles working for the CIA had been involved. But the claims also point the finger at the CIA, which some observers believe could help explain why President Joe Biden backed off last week on declassifying the remaining documents in the case.

So he encouraged his sons to ask him questions about his life.

“My brother asked ‘Who killed John F. Kennedy?’ and his answer was, ‘I didn’t do it but I was in Dallas two days before waiting for orders. We were the cleaning crew just in case something bad had to be done.’ After the assassination, they did not have to do anything and returned to Miami,” his son said on the radio show.

Morales Jr. said his father told them he did not know of the plans to assassinate Kennedy.

“He knew Kennedy was coming to Dallas, so he imagines something is going to happen, but he doesn’t know the plan,” he said. “In these kinds of conspiracies and these big things, nobody knows what the other is doing.”

Morales also knew Oswald, his son claims.

“When my old man was training in a CIA camp…
