Strange Murder At Lake Mohave

Do we have a cold blooded killer stalking campers in the Lake Mead/Lake Mohave area?
From the Las Vegas Sun: Metro Police have released an artist’s sketch of a man described as a suspect in a double shooting Tuesday at Lake Mohave that left one woman dead and her boyfriend wounded.
Police described the man as a white adult male, about 6 feet 4 inches tall and 210 pounds with a muscular build. He had short brown hair and a salt-and-pepper goatee.
He was last seen wearing a yellow button-up shirt, light blue jeans and tan work boots, police said.
He may have been driving a tan, 2000 Jeep Grand Cherokee, police said.
Metro received a call at 9:16 a.m. from a person who had discovered two injured people near the beach of “Six Mile Cove” at Lake Mohave, just east of Searchlight, officials said.
Units from the National Park Service, The Nevada Highway Patrol and Metro discovered two adult victims, a Hispanic man and woman, suffering from gunshot wounds, officials said.
Medics pronounced the woman dead at the scene. The male victim was airlifted to University Medical Center, where he remains in critical condition.
Police say the couple were dating and were on a camping trip when the incident occurred.

This is scary because the media and cops are not releasing any information Do we have case of scorned lover or a drug deal gone bad or a cold blooded murderer who is picking his victims at random at area camp grounds? It almost seems like this couple were executed, based on previous stories.
Because of the lack of information out there, if you visit Lake Mead/Lake Mohave, be very, very careful, especially if you are going camping.
