Brian Costello, the criminal defense attorney representing Trevor P. Fattig, has won a small victory for his client, who previously has been held under house arrest via electronic shackling.

Fattig was charged in April by Eric Zahnd, Platte County prosecutor, with the felony of making a terrorist threat. Costello asked permission from Circuit Judge Owens Lee Hull, Jr., and received the judge’s permission for Fattig to remove his electronic monitoring ankle shackle so that he can work.

Zahnd, represented by assistant prosecuting attorney Bruce Threlkeld, formally opposed Costello’s request.

Fattig and co-defendant Sean M. Amos, both 17, are accused of having made verbal threats to explode ordnance and shoot people at the Platte County High School on April 20, 2006, which was the seventh anniversary of the Columbine school shootings.

Fattig was expelled from the Platte County school district during closed executive session during the June 15 school board meeting. Amos’s status in school is unknown because confirmation cannot be obtained, but it is likely that Amos was also expelled from the Platte County R-3 School District.

Amos and his attorney, Jeffrey Eastman, of Gladstone, had a docket call set for this Thursday at 9 a.m.

Fattig’s next hearing is scheduled for Aug. 10 at 9 a.m.
