Teen's Murder Raises Safety Questions About Kik App

The death of Nicole Madison Lovell, a liver transplant and cancer survivor from Blacksburg, Va., has put Kik-- widely used by American teenagers but not as well known to adults as Snapchat or Instagram -- in the spotlight at a time when law enforcement officials say it has been linked to a growing number of abuse cases. Neighbors say that the day before she died, Nicole showed them Kik messages she had exchanged with an 18-year-old man she was to meet that night.
