But Jason Lawrence Cox, a local farmer, swore in an affidavit that he saw her on June 21 drive past piles of the Etheredges’ belongings, dumped at the side of the road, and onto their farm.

The gang had looted the three family homes on the farm of all but the large mounted heads of an eland and a kudu, according to photos taken before and after the invasion. They used a jackhammer to break through the foot-thick wall of the walk-in safe. The haul from the homes and the farm included 1,760 pounds of ivory, 14 handmade guns, 14 refrigerators and freezers, 5 stoves, 3 tractors, a pickup truck and 400 tons of oranges, the family said.

Eleven days later, a far more violent farm invasion occurred at the home of Mike and Angela Campbell, also here in Chegutu. Mr. Campbell, 76, was the first farmer to take on Mr. Mugabe before the tribunal.

A gang came that Sunday afternoon, pouring out of a pickup truck and a bus, Mrs. Campbell said. Her son-in-law, Ben Freeth, 38, said that he was bludgeoned with rifle butts and that his skull and ribs were fractured. Mike Campbell was also severely beaten.

Mrs. Campbell, 66, said she was dragged by her hair, after her arm was broken in multiple places, and dumped next to her husband. The doctor who treated them in the capital, Harare, signed affidavits confirming the severity of their injuries.

“Mike was so battered, I hardly recognized him,” Mrs. Campbell said. “I didn’t know he was alive until he groaned.” The three of them were loaded into the Campbells’ truck and driven to a nighttime vigil of youth loyal to the ruling party at Mr. Moyo’s base camp, she said.

It was cold, and men poured freezing water over them. Mr. Campbell drifted in and out of consciousness. By the flickering light of bonfires, the youths denounced the Campbells as white pigs, Mrs. Campbell said, and ordered her to sing revolutionary songs. She remembers singing a children’s song instead, which enraged one of her intoxicated tormentors. He charged at her, she said, trying to thrust a burning stick into her mouth.
