Even by Hawaiian standards, the scenic trail at Oahu’s Nu‘uanu Pali Lookout—where more than 400 warriors were forced to jump to their deaths from the 1,200-ft. cliff during a battle in 1795—is hauntingly beautiful.

The doctor who is accused of trying to kill his wife on a Hawaii hiking trail pleaded not guilty on Monday during a court appearance via video conference. Gerhardt Konig's not guilty plea is "a substantive response to the allegation that he tried to kill his wife," his attorney, Thomas Otake, said in a statement.

Prosecutors say an anesthesiologist from Maui tried to push his wife off a cliff during a hike on Oahu, then pulled out a syringe filled with an unknown substance when she resisted.
