Chester and Delaware County police are searching for a 49-year-old man in the fatal stabbing Saturday of a woman in the 300 block of West 22nd Street, said Capt. Stephen Fox, head of the city's detective division.

Fox identified the suspect as Tyrone Blake, who had been living at the house with the woman.

Police declined to release the identity of the victim pending notification of relatives.

Fox said her body was found under a bed in a second- floor bedroom. Paramedics from Crozer Chester Medical Center pronounced her dead at the scene.
