LAFAYETTE, LA—United States Attorney Stephanie A. Finley announced that a Lafayette man pleaded guilty Thursday to using telephone masking technology to harass his ex-wife.

Arthur Craig Wagley, 55, of Lafayette, pleaded guilty before U.S. District Judge Richard T. Haik to one count of telecommunication harassment. According to the guilty plea, Wagley made hundreds of harassing phone calls to his ex-wife from July 4, 2011 to October 7, 2013. Wagley used a telephone spoofing service to call his ex-wife anonymously. He could also set up calls to appear to be family or friends’ numbers and could even disguise his voice using the service. Wagley used these tactics on October 12, 2011, to make 12 phone calls throughout the day, appeared to be someone else and used offensive language. Wagley has been divorced from his ex-wife since 2008. Wagley pleaded no contest and was convicted on September 16, 2010 in the 27th Judicial District Court of Louisiana in St. Landry Parish to felony stalking of his ex-wife. A protective order was issued in 2010 and expired on March 12, 2012.

Wagley faces up to two years in prison, one year supervised release and a $250,000 fine. A sentencing date was not set.

The FBI and the St. Landry Parish Sheriff’s Office investigated the case. Assistant U.S. Attorney Myers P. Namie is prosecuting the case.
