WATERTOWN, MA—Joel Dashner, 34, interpreted acquaintance Lori Rezala's nervous shifting, awkward giggling, and inability to make eye contact at a mutual friend's dinner party as a sign of mounting sexual heat, Dashner said Monday. "I really hit it off with Lori," Dashner said. "We were both too jittery to really say much, but I could feel the spark between us. I'm sure neither of us will forget that magic moment when we bumped hands and spilled each other's drinks." Rezala later told reporters that Dashner "ruined one of her favorite sweaters and stared at [her] all night like he was some kind of crazy person."
