CONCORD, N.H. >> A shooter killed one person in the lobby of New Hampshire’s state psychiatric hospital on Friday before being fatally shot by a state trooper, officials said.

The shooting happened around 3:30 p.m. at New Hampshire Hospital and was contained to the front lobby of the 185-bed facility, State Police Col. Mark Hall said at a news conference. He said CPR was performed on the victim, who later died at Concord Hospital.

Authorities said all patients at the psychiatric hospital were safe, and that the state trooper who killed the shooter was not wounded. No further information was released about the victim, the shooter or possible motive.

Friday’s shooting was the latest act of violence at a U.S. hospital. Medical centers nationwide have struggled to adapt to the growing threats, which have helped make health care one of the nation’s most violent fields.

It came weeks after 18 people were killed and 13 others injured in a mass shooting in neighboring Maine.

The hospital remained in operation but was closed to visitors Friday evening, said Lori Weaver, commissioner commissioner of the Department of Health and Human Services

“This is a difficult and unimaginable day for our employees and for our community,” she said. “We will continue to make resources available in the coming hours and days.”

“Our dedicated staff will continue to provide skilled, compassionate care as they do every day,” she said.

The facility is the only state-run psychiatric hospital for adults in New Hampshire. Located in the capital city, it is part of a large state office park that includes multiple state agencies and is near the city’s high school and district courthouse. The Department of Safety provides security for the hospital.

Democratic U.S. Rep. Annie Kuster called the shooting “horrifying” in a statement that asked the public to stay away from the hospital while police were still on the scene.

“Thank you to the State Police Officers who responded to the scene so quickly,” Kuster said in a statement. “My thoughts are with the victim, their family, and the Concord community.”

Other members of the state’s congressional delegation also released statements of support.

“The state immediately mobilized, and first responders and law enforcement are on the scene,” Gov. Chris Sununu said in a statement. “We will provide as many details as possible as this situation unfolds.”
