JACKMAN — A man who died Saturday night in an exchange of gunfire with U.S. Border Patrol agents faced domestic-violence charges in March, but reached a plea agreement on lesser charges, according to court records.

Charles E. Robinson, 75, of Jackman, shot one of the agents before he died at a home on Long Pond Road, according to Martha Demeritt, executive assistant to Attorney General William J. Schneider. The patrol agent, whose identity has not been made public, was treated at a hospital and released, Demeritt said.

Police dispatchers received a 911 call about 7:15 p.m. Saturday reporting a domestic disturbance. The female caller reported an oral argument with Robinson, described by Demeritt in an email as the caller’s partner. The woman told dispatchers they needed an ambulance because Robinson was intoxicated and had fallen.

Robinson reportedly threatened to kill the woman if she called for assistance and reportedly disabled the telephone in the residence while she was talking with emergency dispatchers, Demeritt said.

The closest law enforcement agency was the U.S. Border Patrol station in Jackman, about three miles away. Two U.S. Border Patrol agents responded to the call, Demeritt said.

“When entering the residence, they were met with gunfire and returned fire,” according to Demeritt. “One of the agents was struck by the gunfire and suffered superficial wounds. The agents retreated from the residence and the Maine State Police Tactical Team was activated.”

Demeritt said when attempts by tactical team members to establish contact with Robinson were unsuccessful, they entered the home and found Robinson dead from apparent gunshot wounds.

Detective Lt. Carl Gottardi of the Somerset County Sheriff’s Department said several deputies also responded to the initial call. Gottardi said he obtained a search warrant for the residence and property, which the tactical team used to enter the home, he said.

Robinson had been arrested by state police in March and charged with domestic-violence criminal threatening in an incident also involving a woman, court records show. The woman was described in that case as being a member of his family or household. He also was charged with disorderly conduct by using offensive words or gestures.

Robinson allegedly said he would kill her “if anything happened to the cats,” according to the court documents.

The domestic-violence criminal threatening charge was dropped in April when Robinson pleaded guilty to the disorderly conduct charge. He was ordered to serve 12 hours in jail.

The Attorney General’s Office is investigating the use of deadly force by the two Border Patrol agents. The office is being assisted state police and the Office of the Chief Medical Examiner.

It is the policy of the U.S. Border Patrol and other federal law enforcement agencies to withhold the names of the agents until the attorney general issues his final report, Demeritt said.
