PORTLAND — The man accused of sending threatening letters to Gov. Paul LePage is scheduled to be in U.S. District Court in Portland Wednesday for a detention hearing.

Michael R. Thomas, 50, of 1125 Brighton Ave. was arrested Friday in connection with threatening letters sent to LePage. The letters said the writer would be willing to sacrifice his life to shoot the governor.

A forensic DNA analysis at the Maine State Police crime laboratory used biological samples taken from a stamp from one of the three envelopes, developed a DNA profile and matched it to one already in a federal database.

The U.S. Attorney’s Office is seeking to have Thomas held pending trial rather than be released on bail, according to his lawyer.
