HONOLULU - The sister accused of deliberately driving off the edge of a Maui cliff killing her twin sister faced day three in court Wednesday.

On the last day of testimony for Alexandria Duval, investigative experts were called to the witness stand to examine calculated data chronicling the moments before the SUV swerved over a 200-foot cliff, killing Anastasia Duval in the passengers’ seat.

Alexandria faces second-degree murder charges, and waived her right to testify in court.

If found guilty, Duval faces life in prison.
