A U.S. Army veteran in Philadelphia was sentenced to more than five years in prison after federal authorities say he stole the personal information of his fellow service members and used it to harass and stalk them over past grievances.

U.S. attorneys in the Eastern District of Pennsylvania say Alpha Omega Mayhue, 40, worked with unnamed co-conspirators to impersonate his victims and make unauthorized transactions at banks, credit unions, the Federal Trade Commission and elsewhere.

He terminated their military and disability benefits, rerouted direct deposits, changed account information and reported their debit cards as stolen, the Justice Department said in a statement.

In one case, Mayhue cyberstalked a service member, claiming he was surveilling her and making sexual threats.

Mayhue was indicted last year by federal authorities on charges that included conspiracy to commit identity theft, seven counts of misusing a social security number, seven counts of aggravated identity theft and 21 counts of making false statements.

The sentence handed down in Philadelphia on Monday requires Mayhue to serve 65 months in prison followed by three years of supervised release. He will also be required to pay a $3,100 special assessment for stealing the personal information.
