An Allentown man is heading to trial on charges he stabbed his girlfriend to death.

A preliminary hearing was held Thursday for Jonathan Schaffer, and all charges were held for court.

Schaffer, 31, stabbed Lauren Wolstenholme to death inside their apartment on South 18th Street in September, police said.

Schaffer claimed Wolstenholme was coming at him with a knife and said he stabbed her in self-defense.
