Former GBMC physician found dead in Texas

The Baltimore Sun

A former physician at Greater Baltimore Medical Center was found dead Sunday in her Laredo, Texas, swimming pool, a death that police are investigating as a possible homicide.

Dr. Marissa Christine Keene, 40, who worked as a staff physician at the Towson hospital from 2000 to 2006, drowned, police said.

Joe Baeza, a spokesman for the Laredo Police Department, said yesterday the death has not been officially ruled a homicide, but that investigators are continuing to examine her residence and backyard. "It is a complicated case," Baeza said.

Mark Alan Keene of Austin, Texas, her twin brother, said more than 1,000 people waited in line for nearly five hours to pay their respects Tuesday night.

Her brother said she set up an obstetrics and gynecology practice after moving to Laredo a year ago to allow her more time with her son, 10, and twin daughters, 8. "She gave absolutely every ounce of herself to her three children," he said.

Her marriage to Dr. Christopher deFilippi, a cardiologist and associate professor of medicine at the University of Maryland School of Medicine, ended in divorce.

Born in San Antonio, Dr. Keene attended Trinity University there, earning a bachelor of arts in biology. She received her medical degree in 1993 at the University of Texas' Southwestern Medical School in Dallas, with training in obstetrics and gynecology. While at GBMC, she lived in Roland Park and later Ruxton.

Besides her brother, she is survived her son, Devon Anthony deFilippi; twin daughters, Mia Isabella and Alicia Della deFilippi; and her parents, Dr. Roger Hampton Keene and Dr. Gladys Cronfel Keene of Laredo.

A funeral Mass was offered yesterday in Laredo.
