A father and a mother were stabbed by their adult son Tuesday morning in the Franconia section of Fairfax County, police said.

Police were called to the scene in the 6000 block of Sweet Pea Court around 7 a.m. for a report of a stabbing, said Fairfax County police Second Lt. John Wallace. The victims, a 64-year-old man and a 54-year-old woman, were found suffering from stab wounds to the upper body, Wallace said.

The son had fled the scene and was later taken into custody by Fairfax County police and Virginia State Police, Wallace said. It’s unclear if any charges have been filed.

The couple were transported to the hospital, where they are in stable condition, Wallace said. Their names have not been released.

Police have not said what prompted the stabbing.
