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

Police dispatchers got a 911 call about 7:15 p.m. Saturday reporting a domestic disturbance. The female caller reported an 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 disabled the telephone in the home while she spoke with emergency dispatchers, Demeritt said.

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

“When entering the residence, they were met with gunfire and returned fire,” said 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 tactical team members could not establish contact with Robinson, then entered the home and found Robinson dead from apparent gunshot wounds.

Detective Lt. Carl Gottardi of the Somerset County Sheriff’s Department said he got a search warrant for the home and property, which the tactical team used to enter the home.

Robinson was arrested by state police in March and charged with domestic-violence criminal threatening in an incident 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 disorderly conduct. 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 Medical Examiner’s Office.

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.
