Prosecutors in Dallas say a member of a "swatting" ring that made hoax 911 calls has pleaded guilty to computer-related conspiracy and retaliation counts.
Jason Allen Neff of Omaha, Nebraska, faces up to five years in federal prison in a plea deal over the investigation since 2006.
Six other people have been convicted and sentenced to prison over bogus emergency calls that sent SWAT law enforcement teams to various locations.
Neff pleaded guilty Tuesday to aiding and abetting the conspiracy to use access devices to modify telecommunications instruments and to make unauthorized access to protected telecommunications computers. Neff also pleaded guilty to obstruction by retaliating against a witness, victim or informant.
Neff was arrested in 2011 in Jackson, Missouri, and remains in custody pending sentencing.
