Transcript for California Officials Hunt for Suspected Murderer, Kidnapper
We have to switch gears to this. Police searching for an armed and dangerous killer wanted to are a string of crimes including a murder, kidnapping and shooting two sheriff's deputies. ABC's kayna Whitworth is on the scene in jawbone canyon, California. Good morning, kayna. Reporter: Hey, George, good morning. This is an intensive manhunt and have seen a search helicopter take off this morning. Now, residents in this area are on lockdown and all the while authorities think this man has been hiding in abandoned structures like this. They are scattered all throughout the jawbone canyon. In thth this morning a search for a man they think is armed and extremely dangerous. Problematic for us to conduct a search. We do know that he's willing to engage law enforcement with a gun. Reporter: It began a week ago on July 28th in the remote wilderness east of Bakersfield, California. The suspect first spotted in a cabin near twin oaks where he held three young men hostage at gunpoint. The suspect left the structure and the three 20-year-olds decided that they -- because he had threatened to kill them that they were going to run for their lives. Reporter: Two days later ten miles east of the first cabin in jawbone canyon authorities linking the fugitive to a retired dentist found shot to death in his cabin. And on Saturday, less than five miles away in Kelso valley the suspect described as 30 to 35, a white male in military style clothing shot and wounded two S.W.A.T. Team members searching for him in an abandoned mobile home. Police and S.W.A.T. Teams narrowing in on a five-mile radius of remote desert. Residents on lockdown. I am concerned. There's a lot of ways to get around the mountains and landscape. Reporter: The sheriff's department had to bring in their atv team for part of the search and looking in an old tungsten mining area which mean authorities fear there are plenty of mine schaafs and caves for him to be hiding in. The search covering peaks as high as 7,000 feet and with temperatures in the triple dig digits officials tell ABC news they're counting on the suspect to slip up. What we're kind of hoping is that he doesn't stay hydrated and then you start making mistakes. Reporter: Authorities think this really could come down to water here. And they also added that there are livable dwellings in the canyon as well. People keep those stocked with, yes, guns and water. And, Amy, locals say that if he ever lived in this area he would know that. All right, kayna, thanks so much.
