AMBER ALERT suspect, Tad Cummins, allegedly searched the topic of teen marriage days before disappearing with 15-year-old, Elizabeth Thomas.
The Tennessee Bureau of Investigation said they discovered a "troubling pattern of behavior" by 50-year-old Cummins prior to his disappearance with Thomas.
Three days before the kidnapping, Cummins did online research about his Nissan Rogue, trying to figure out if certain features could be tracked by law enforcement.
Investigators also found that five days earlier, on March 5, Cummins did similar online searches on the topic of teen marriage.
Tuesday, 15-year-old Ashlee Riggins, Elizabeth Thomas' best friend, pleaded with Elizabeth to get away from Cummins if possible.
"I know that you may love him and think he's perfect, but he's not," said Riggins, referring to Cummins. "I love you, and there's so many people here who need you and want you back."
