Sin Chhoeum,
seamstress, survivor of Cambodian genocide

Sin Chhoeum, 101, who survived more than three years of forced labor during the Cambodian genocide before immigrating to the United States in 1983, died Aug. 5 at a hospital in Frederick, Md. Her son, Leth Oun, confirmed the death but did not know the precise cause.

Mrs. Sin was born in Battambang City, in northwestern Cambodia, and worked as a seamstress and tobacco roller. Soon after the communist Khmer Rouge seized power in 1975, her husband — an army officer — was executed, and the family was split up. Mrs. Sin and two of her three children were sent to different forced-labor camps, where they were fed meager rations and spent up to 18 hours each day farming and building dams among the rice paddies.

Nearly 2 million Cambodians, about a quarter of the population, died before Vietnam invaded, ousting dictator Pol Pot in 1979. By then Mrs. Sin was in her early 60s, and the family’s home in Battambang had been destroyed. Reuniting with her children, she left her infant daughter with her mother-in-law, who had cared for the girl during the genocide, and traveled on foot to the Thai border with her two older children, in search of better fortune.

They were eventually picked up by a refu­gee organization and immigrated to the United States, where Mrs. Sin lived in Silver Spring, Md., and Philadelphia, volunteering at Buddhist temples, before retiring to Frederick in 2007.

Her youngest daughter remained behind in Cambodia, but Mrs. Sin, who was ailing in recent months, had been unable make the trip. “I told her when she’s recovered I’ll buy her a ticket, first class,” her son said. “She was so sick that if she went, we knew she wouldn’t make it back.”

Helen Bobinger,
homemaker, gift shop worker

Helen Bobinger, 97, a homemaker who later worked at a gift shop, died Aug. 2 at a hospice center in Pasadena, Md. The cause was pneumonia, said her daughter, Jan Armstrong.

Mrs. Bobinger was born Helen Phillips in Snowville, Va. She grew up there and, after the age of 12, in Baltimore. After her children were grown, she worked at a gift shop in Bladensburg, Md., where she lived for many years. She later lived in Severn, Md., and was a member of St. Ambrose Catholic Church in Cheverly, Md.
