A sword-wielding 17-year-old boy stabbed his 15-year-old ex-girlfriend in the thigh and throat and injured two of the girl's relatives in a Paradise Hills home, police said.
The girl was in fair condition at UC San Diego Medical Center on Wednesday afternoon, a hospital spokeswoman said. The girl's mother received stitches in her hand after the Tuesday attack and was released, police said. The girl's sister was treated for a superficial stomach wound and released.
The youth was still being sought Wednesday afternoon.
Police Lt. Rulette Armstead said the youth is a former San Diego resident who now lives in another state.
"There was speculation that he might have gone out of state, but we don't know that for a fact," she said.
Police spokesman Bill Robinson said the 6:37 p.m. incident in the 1900 block of Saipan Drive stemmed from a reconciliation attempt by the boy.
