ALLENTOWN, Pa. -

A trial is underway in Lehigh County for Na Cola Franklin, a woman accused of killing her fiancé just hours before their wedding.

A jury was selected for the trial, and testimony began Tuesday afternoon.

Franklin fatally stabbed her husband-to-be, Billy Brewster, inside their home on Olympic Circle in Whitehall Township on Aug. 11, 2012, police said.

The couple was due to be married later that day. Their four children were at home at the time of the killing, police said.
