An Australian man was acquitted Thursday in the murder of a young woman who fell from his balcony two years ago after the two met through the popular dating app Tinder. What, exactly, caused 26-year-old Warriena Wright to plunge 14 stories is not known, but the encounter between the couple -- much of which was captured on an audio tape -- has prompted the question: Are mobile dating apps safe? The answer is complicated, according to dating experts and behavioral psychologists. "These incidents are very rare," said Sameera Sullivan, a relationship expert and psychologist who founded the matchmaking service, Lasting Connections, in 2012. "There's always going to be bad people out there," said Sullivan.
Faith Hedgepeth was bludgeoned to death four years ago inside her off-campus apartment at the University of North Carolina Chapel Hill in a case that remains unsolved. The killer left behind a chilling note and traces of DNA -- which a forensic technology company has now used to create a 3-D sketch of what the suspect might look like. A "snapshot tool" developed by Parabon NanoLabs has created a 3-D image of the killer based on DNA traits, and authorities are hopeful the sketch could lead to a break in the case. The Reston, Va.-based Parabon Nanolabs, with funding from the Department of Defense, debuted the breakthrough type of analysis called DNA phenotyping in 2015 which the company said can predict a person's physical appearance from the tiniest DNA samples, like a speck of blood or strand of hair. The DNA phenotyping service, commercially known as "Snapshot," could put a face on millions of unsolved cases, and generate investigative leads when the trail has gone cold.
