Two security guards at the Wackenhut Corp, were arrested yesterday and charged in what police sources said was the contract murder of the wife of one of the men.

Police said they were called about 1.45 a.m. by Raymond A. Poellot, 23, who told them that he had found his wife, Patti Johnele Poellot, stabbed to death when he returned home to their apartment from work at the Wackenhut Corp. in Takoma Park.

Police said Mrs. Poellot, who lived with her husband at 5619 Regency Park Ct. in Suitland, had been stabbed to death. Sources said her throat had been slashed.

After being questioned by police,Poellot was arrested at 8:47 a.m. and charged with conspiracy to commit murder, police said. Ninety minutes later, James R. Hamilton, 20, of 3200 12th St. SE, Washington, Poellot's supervisor, also was arrested and charged with murder.*tAccording to police, Poellot allegedly believed that his wife had been seeing other men and agreed to pay Hamilton and another man $2,500 each to kill his wife.

Poellot called police after finding the body and, according to two sources, "was just too cool about it. They thought he was involved right away. He called up as if he were reporting a traffic ticket."

Marine Corps spokesman Paul Chapman said last night that Raymond Poellot enlisted in the Marines in November 1974 after growing up in Longmont, Colo. He was stationed in Washington while on active duty, where he met his wife, also a member of the Marine Corps.

Chapman said Raymond Poellot was awarded a meritorious unit citation and a good conduct medal and was released fron active duty on Jan. 14, 1979, although he remained in the Marine Corps reserve. His wife was still on active duty.

Police alleged that Poellot was planning to pay for the murder through an insurance policy he had taken out on his wife. No money had yet changed hands, police said.

Neighbors in the Regency Park apartments, located just across the District line, said they did not know the Poellots. But one neighbor, who asked not to be identified, said that he heard "yelling," coming from the Poellot apartment "on several occasions" during the past two weeks.

Under Maryland's new death penalty law Raymond Poellot and Hamilton, along with a third man would face a possible death penalty if convicted of a contract murder.

Poellot and Hamilton were both employed as security guards at Wackenhut, sources said. Poellot began working there, they said, shortly after his discharge from the Marines.

Both men were being held last night without bond in the county detention center in Upper Marlboro pending a bond hearing this morning
