A Massachusetts man has pleaded guilty in a Texas federal court to making phony 911 calls via the Internet, sending police to a quiet Dallas-Fort Worth family’s home, a practice known as “Swatting.” Last Tuesday, Matthew Weigman, 18, admitted to making the 911 calls during 2006, when he claimed to have shot his family with an AK-47 rifle. He used a VoIP telephone connection to “spoof” the address of someone he had met during a “party line” call, court documents say. Weigman also admitted to several other 911 calls, to threatening a Verizon technician who was helping the FBI investigate the 911 calls, and to using the telephone network to fraudulently obtain products and services. He faces up to 13 years in prison when he’s sentenced later this year. Two co-defendants await trial in the case, and one co-defendant pleaded guilty and was sentenced to two years in federal prison.
