Dr. Gerhardt Konig faces murder trial for allegedly pushing wife off cliff during Hawaii hike.

An attempted murder trial in Hawaii is concluding for Dr. Gerhardt Konig, an anesthesiologist accused of trying to kill his wife, Arielle Konig, during a hike on the Pali Puka trail. Prosecutors allege he pushed her toward a cliff, struck her with a rock, and attempted to stab her with a syringe, while she testified she fought back and was rescued by hikers. Konig denies the charges, claiming self-defense and that no syringe was found at the scene. The case has centered on marital tensions and conflicting accounts, with closing arguments expected soon.
