Killing of Nicole Lovell raises the question of how to keep children safe on social media

There is still so much we do not know how a 13-year-old Blacksburg, Virginia, the girl got to know a 18-year-old freshman Virginia Tech, before he allegedly stabbed to death. What we know is a little bit more for a possible motive for the death of Nicole Lovell, a junior high school student. David Eisenhauer, a college track and field athlete, believed that they had an inappropriate relationship with Lovell and stabbed to death because he threatened to expose their relationship, according to a law enforcement official. But how do you meet? How did the alleged relationship? Points are facing an online network, after police arrested Eisenhauer with tips and leads from social media. We also know that Lovell was active in social media, including entries in a group on Facebook called teen dating and courtship, which has been closed since.
