One person was seriously injured in a small plane crash in Newport, New Hampshire, on Sunday.

Newport police and fire responded to Parlin Airfield shortly after 1 p.m. Sunday for a reported plane crash. When they arrived, they said they found a private, single-engine plane in a wooded area off the end of the grass runway.

An off-duty Newport police employee had witnessed the crash, and assisted Newport fire personnel in removing the pilot from the plane. The pilot sustained serious, but non-life-threatening injuries and was flown by medical helicopter to Dartmouth Hitchcock Medical Center in Lebanon.

The pilot’s name has not been released. They were the only one in the plane at the time of the crash.

The cause of the crash is under investigation by the Federal Aviation Administration, with assistance from local, state and federal authorities.

Anyone who may have witnessed the crash or has further information is encouraged to contact police at 603-863-3232.

The New Hampshire Attorney General’s office said a man who allegedly shot two people in Hampton Beach died by suicide when confronted by police.

In a joint statement, the state Attorney General’s office, State Police and Hampton Police Chief Alex Reno identified the man as Tyshawn Cooper, 21, of Taylors, South Carolina, who was declared dead at the scene.

Initially, officers responded to reports of a shooting at about 1:19 a.m. Sunday. Police said they located a man and woman suffering from gunshot wounds in the area of 29 Ocean Boulevard.

Officers found a man who matched the description of the suspected shooter at the intersection of P Street and Ashworth Avenue. During their interaction, police said the man pulled out a handgun and raised it, then shot himself in the head while an officer also fired.

The Office of the Chief Medical Examiner performed an autopsy Sunday and determined the cause of death was suicide.

The 23-year-old man and 25-year-old woman who were shot were taken to the hospital for treatment of their injuries.

The shootings remain under investigation.

The Attorney General’s office said it will also investigate the police officer’s use of deadly force, though the officer that fired did not cause Cooper’s death. No other injuries were reported.

Robert Fiske and his girlfriend, Meghan Foote, were among the first people to arrive in downtown Concord for the Fourth of July Parade that marked 250 years since the signing of the Declaration of Independence.

“I love American history, all the way back from the Revolutionary War to now,” said Fiske.

Like many other attendees, Fiske was particularly looking forward to seeing the members of Concord’s Veterans of Foreign Wars Post 1631, who would be marching down Main Street.

Mary Ellen House and her granddaughter Anastasia Esman seated themselves right across from the State House Plaza, where the Nevers’ Second Regiment Band would be playing throughout the parade.

“I love the band and the drums,” House said. “We were down on Storrs Street, and we saw a lot of fun things down there.”

Of the many antique vehicles in the procession, including cars, a fire engine, police cruiser and Abbot Downing Concord Coach, one was a first: A plane going down Main Street.

Jennifer Kretovic, city councilor and co-chair of the committee that organized the parade, was particularly proud of that.

“The first airplane to go down Main Street, our committee should be so proud,” she said.

Following the parade, the festivities moved to the State House Lawn, where government officials honored New Hampshire’s rich history and involvement in the American Experiment.

Senator Maggie Hassan called on the words of George Washington when he said that American Independence was “little short of a standing miracle,” and she asked attendees to reflect on the “unlikely nature” of America’s founding and survival through 250 years.

Speeches concluded with a reading of the Declaration of Independence, after which the Lafayette Reenactors in attendance conducted a musket and cannon salute on the lawn.

The evening was capped off by a fireworks display at Memorial Field.
