The son of a Maui doctor testified in court that his father confessed to him over FaceTime about attempting to kill his stepmother on a hiking trail in Hawaii last year.

The testimony came during the attempted murder trial of Gerhardt Konig, a Hawaii-based physician. According to the son's testimony, his father appeared on the video call with blood visible on his shirt when he allegedly admitted to the attack.

Prosecutors allege that Konig attempted to kill his wife, Arielle Konig, during a hike by trying to push her off a cliff. The charges also include allegations that he attempted to inject her with a syringe and struck her in the head with a rock during the incident.

The son's testimony represents a key piece of evidence in the prosecution's case against the doctor. The FaceTime confession occurred after the alleged attack on the cliff trail but before Konig's arrest.

The trial is ongoing as prosecutors seek to prove their case that Konig deliberately attempted to murder his wife during what was supposed to be a hiking excursion. The defense's strategy and response to the son's testimony has not been detailed in current proceedings.
