The threat at the Pasadena hospital was received from an IP address at 5:40 a.m., prompting police officers, fire personnel and K-9 units to search the hospital, according to city spokesperson Lisa Derderian. The FBI describes 764 as a violent online network that seeks to coerce children into engaging in violent and sexual acts against themselves, animals and other minors. The Pasadena Police Department and the FBI are continuing to investigate in hopes of identifying the caller who made the threat. Swatting is just one criminal element associated with 764, which federal authorities have characterized as a network of nihilistic violent extremists.
