An alumna was one of 12 people killed in a plane crash in Costa Rica Sunday, The Washington Post reported.

Irene Ginsberg Steinberg, 51, graduated from GW in 1988 with a bachelor’s degree from the Columbian College of Arts and Sciences. She, her husband and three children, were on vacation when a small plane they chartered crashed in the Guanacaste region in northwestern Costa Rica on the way to the capital San Jose. A Floridian family and two Costa Rican crew members also died in the crash, The Post reported.

The family lived in Scarsdale, N.Y., but Irene Steinberg had grown up in Potomac, Md. After graduating from GW, Steinberg attended New York University, where she studied social work and later taught classes.

She met her husband, Bruce, in her 20s, and together they had three sons. Their youngest son, Matthew, was in eighth grade, while their two older sons, William and Zachary, studied at the University of Pennsylvania and Johns Hopkins University, respectively, according to The Post. All of them were killed in the crash.

The cause of the incident is still unknown.
