AUBURN — A Minot man who police say shot up his Verrill Road home and caused an armed standoff for more than six hours in December pleaded not guilty Thursday to charges stemming from the incident.

Michael Callahan, 44, was charged with two counts of domestic violence criminal threatening, six counts of reckless conduct and a count of aggravated criminal mischief. Each count is punishable by up to five years in prison and a fine of up to $5,000.

Callahan appeared in Androscoggin County Superior Court accompanied by his attorney, James Howaniec.

Callahan denied all charges.

Howaniec told the judge his client may be pursuing an affirmative defense of not guilty by reason of insanity. A judge approved a mental evaluation for Callahan in January. Howaniec said he is reviewing the results.

The case was continued to trial. Callahan was released on $10,000 cash bail.

State police officers were called to Callahan’s house at about 10:30 p.m. on Dec. 21. A family member had fled the house when Callahan began shooting inside, police said. An overnight standoff ended peacefully with Callahan surrendering to police about six and a half hours later, after a tactical team member returned fire. Callahan fired about a dozen rounds, police said.

He was ordered not to have contact with his wife, his daughter or his son.
