PART 2

Investigators say romance scams, in particular, are on the rise. The con on Manti Te'o never turned to money, but investigators say most do.

Prosecutors are about to launch a brand, new unit to battle cyber crimes.

KITV4 talked with the man leading the fight to stop them, and others, who cheat, prey, and pretend to love.

"He fell in love with this, let's say, this character," began Dr. Phil McGraw on the Dr. Phil Show on Thursday.

"In a lot of these cases, especially in the romance scams, they start out very innocent," said Chris van Marter, who is a deputy prosecutor, and the head of the white collar crimes unit at the prosecutor's office.

"I love you so much. Sweet dreams," said what appeared to be a woman's voice on one of the voice messages to Manti Te'o.

Her name was Lennay Kekua.

She was 22-year-old Ronaiah Tuiasosopo's made-up woman.

She would soon to become Manti Te'o's fake online girlfriend.
