CLAY, N.Y. — Police have accused a man of fatally stabbing a school librarian and raping her child after carjacking them at a central New York mall.

They say the woman was leaving a gymnastics class with her 10-year-old daughter when the attacker stopped them at the mall in Clay at about 9 p.m. Thursday.

Troopers say 29-year-old David Renz raped the girl and killed the woman in the Syracuse suburb. The girl managed to escape.

Trooper Jack Keller said Friday that the woman died Thursday night and the child is hospitalized.

Renz, of Cicero, has been charged with murder, rape and kidnapping. It wasn’t initially known if he has a lawyer.
