Philippine Rebels Free Peace Corps Volunteer : Pacific: Communist guerrillas release the American and a Japanese captive they had accused of spying.

Communist guerrillas freed a kidnaped U.S. Peace Corps volunteer and a Japanese rural technician today after 50 and 65 days in captivity, respectively.

Timothy Swanson, 27, of Cheyenne, Wyo., was turned over to representatives of the International Red Cross in his Patag village home in the mountainous municipality of Silay on Negros Island, 300 miles south of Manila.

“I’m really glad to be out. I’m very tired; I’m going to pass out,” Swanson said during turnover ceremonies at a rebel campfire. He said the rebels were “very good” to him.

Swanson was flown to Manila later in the day. He was expected to return shortly to Cheyenne after a medical examination, U.S. officials said.

“I’ll tell him it’s about time he got home,” his mother, Lynne Swanson, said on hearing in Wyoming that her son had been released.

Her husband, Leonard, said, “I don’t know exactly what we’ll tell him when when we see him, but for sure we will tell him we love him. We’ll be so happy to see him, out of danger and home.”

Negros Gov. Daniel Lacson said Swanson’s release was delayed because of the rugged terrain and failure by the negotiators to locate the appointed place for the release. But he said that before nightfall, the guerrillas came down from the hills with Swanson to turn him over to civilian negotiators.

Earlier today, the guerrillas of the Communist New People’s Army turned over Fumio Mizuno, 36, to his Filipina wife and two children at a sugar plantation on the outskirts of nearby Murcia.

Swanson and Mizuno, who appeared tired but otherwise in good shape, were examined by representatives of the Red Cross and doctors before the rebels released them.

Swanson was kidnaped June 13 from Silay. On June 27, Washington ordered the suspension of the 29-year-old Peace Corps program in the Philippines and recalled its 261 volunteers.

The suspension was prompted by reports the NPA planned to kill or kidnap the volunteers in an escalation of its terrorist drive against Americans to press demands for the withdrawal of U.S. forces.

Mizuno is training director of a Tokyo-based private aid group called Organization for Industrial, Spiritual and Cultural Advancement.
