A second person, Claire McMullen, 60, was shot in the arm.
She did not have identifying details for the patient, and could not confirm whether the injuries were caused by gunshots or something else. The two injured were then transported to area hospitals by Pelham Fire Department ambulances.
The Pelham Police Department provided active shooter training to members of the church within the past year, Roark said.
Lowell General Hospital has received one patient from the incident, hospital spokesperson Angela Strunk tells CNN. Police say the man arrived and began shooting after the ceremony started.
Pelham is located about 40 miles (64 kilometers) south of Concord, New Hampshire's capital. The service was in honor of a minister at the church who was shot and killed in his home October 2. The affiliate reported he was shot inside a home in Londonderry and that a suspect was arrested.
Police were called to the church shortly after 10 a.m.in Pelham, a town of about 13,000 on the border of MA.
A memorial service for Luis Garcia was set to be held at the church at noon Saturday.
The shooting was reported at New England Pentecostal Church around 10 a.m. EST. According to his obituary, he was a minister at the church. A man has been charged with his death and is serving time in jail.
Those planning to attend the Garcia service were shocked by the shooting.
