Over two years after the bodies of several women were discovered in Oregon and Washington, officials are expected to give an update Tuesday on the Jesse Lee Calhoun case.

The quick pace of the murders Calhoun is accused of committing after his release indicate Calhoun felt “invincible,” says forensic psychologist and author Katherine Ramsland. “He thinks he’s going to get away with it, and so he’s escalating, he’s wanting to do this more,” she told “Banfield.” “He may be developing a sort of addiction to it.”
