A woman who identified herself as his grandmother said Monday in a phone interview that she did not know how to contact her grandson. He did not return multiple phone messages Sunday and Monday. Scaglione's biography vanished from KCCI's website over the weekend.

On Twitter, he had more than 13,200 followers. Scaglione's Twitter and Facebook accounts were apparently deleted Sunday. Several boys describe Scaglione asking increasingly personal questions, including requests to get lunch, to come to his house or to send pictures of their genitals. In both the posts and in interviews with the Register, half a dozen youths described Scaglione pursuing personal relationships with them over social media, in some cases sending unsolicited pictures of genitals or of his shirtless upper body to 17-year-old boys in the Des Moines area. The Des Moines Register contacted several people associated with the tweets. On Sunday, several Twitter accounts posted allegations that Scaglione, 26, has used social media to pursue sexual relationships with boys younger than 18.
