Ciancia's family was becoming concerned after receiving text messages from him indicating he was unhappy. Ciancia's father called New Jersey police, who contacted Los Angeles police and asked them to check on Ciancia, according to police. He was already on his way to the airport -- police had missed him by less than an hour, U.S. Rep. Michael McCaul told CNN.
