KEENE, N.H. — Police are investigating a homicide after a teenager from Orange was found dead from a gunshot wound in a parking lot on Winchester Street.

New Hampshire Attorney General John Formella, in a written statement released Wednesday afternoon, said Christian Walker, 17, of Orange, was found fatally shot early Wednesday morning by police responding to a 911 call. He was taken to Cheshire Medical Center in Keene and was pronounced dead at 1:49 a.m.

Wednesday afternoon, Formella wrote, Associate Medical Examiner Dr. Abigail Alexander conducted an autopsy and concluded the cause of death to be a single gunshot to the abdomen.

“While the exact circumstances surrounding the shooting remain under active investigation, all parties involved have been identified,” Formella wrote. “There is no known threat to the general public at this time.”

Franklin County Technical School, where Walker studied automotive technology, notified faculty and staff about the incident at approximately 4 p.m. Wednesday, according to Superintendent Rick Martin.

Martin said he called Walker’s family when he was made aware of the student’s death at roughly 1 p.m. He then contacted Care Solace, the district’s mental health counseling firm, as well as a contractual social worker.

From 1 to 3 p.m. and 5 to 7 p.m. on Thursday, June 26, grief counselors will be available at Franklin Tech to support any students or staff members. Additionally, Martin said a mental health counselor will be on standby for further follow-ups.

“We are all-hands-on-deck in supporting our students and our community,” Martin said. “Our hearts, thoughts and prayers go out to the students, family, friends and those impacted by a tragic and untimely death. ... [He was] taken from us way too soon.”
