DATELINE's WILD, #WILDWEB Series Returns Friday with 'Vampires'

On Friday, May 17 at 8pm/7c "Dateline's" Wild, #WildWeb returns with a full hour of undercover investigations that further reveal the hidden world of online classified ads. "Dateline's" Chris Hansen answers a series of online advertisements and what he reveals may make people think twice the next time they surf the web.

As "Dateline" hidden cameras roll, Hansen confronts several individuals who seem to be trying to make money off of complete strangers. Jessica Travers describes herself as a 35-year-old single mother in search of love with an older man. She is willing to relocate but asks for a few thousand dollars to cover her moving expenses. When Hansen meets Travers in person, it appears she is a teenager using someone else's photo in effort to lure an older man online.

Hansen also meets several individuals who say they are vampires. In Atlanta, he answers an ad from Sam, a college student looking for someone to donate their blood.

During the hour, Hansen meets a woman who puts her child up for adoption on Craigslist. "Dateline" discovers that she has a criminal background and is accused by police of ripping people off. Cameras roll as Hansen confronts an Arizona mechanic who appears to be significantly overcharging customers for simple repairs, and a man who sells "all-natural" pills that appear to be potentially dangerous knock offs of prescription drugs like Viagra and Cialis.

Chris Hansen will also host a Google + hangout on Thursday, May 16 at 12:30pm ET. For information on how to join the hangout, follow us on Twitter at @datelinenbc. In addition, Hansen will participate in a live Reddit "Ask Me Anything" Q&A session on Reddit.com at 2:00pm ET.
