PHOENIX -- When Drew Maras left the Marines in 2003, his life took a turn. He became a believer in the paranormal. Those beliefs grew and became more extreme through the years, to the point where he dedicated his life to conspiracy theories involving aliens and the Apocalypse.
Maras authored a book about his conspiracy theories, including his belief that the world would end this December.
"We cannot sit idly by with 2012 right around the corner," Maras preached on a radio show last year. He told the host that he considered it his duty to warn the public of the coming Apocalypse.
According to interviews on various paranormal radio programs and podcasts, Maras was fascinated by places like the Bradshaw Ranch in Sedona, made famous by alien sightings and paranormal activity.
It's not far from the scenic overlook where deputies believe Maras murdered two people from New Hampshire, seemingly unprovoked.
"It's difficult," said Sheriff Joe Arpaio. "We can't talk to him since he's dead. We won't find out what his motive was."
Energy vortexes were another interest of Maras. People find the mysterious energy fields in Sedona healing and flock to meditate near them.
Maras believes aliens are also attracted to the vortexes.
"The aliens harvest the magical power [from the vortex] in a way that's still foreign to us," he said on another paranormal podcast.
The host of one of the podcasts, Jordan Cline of Whispers Radio, called Maras 'extreme' in his beliefs, and called his crime spree inexplicable.
"I remember doing the show [with Drew Maras] thinking, 'This guy is pretty hardcore in his beliefs,'" Cline said. "It's really a shame. I hate to hear that somebody I had on my show did such a horrible thing and disrupted so many lives."
While Maras' views were unconventional, investigators say they do not explain what led him to murder.
