Concord, NH – New Hampshire State Police are renewing their call for public assistance in a decades-old homicide case involving a Manchester teenager fatally shot inside his car in 1974.
According to the New Hampshire Cold Case Unit, police were called to Hermit Road in Manchester at 3 a.m. on November 24, 1974, after receiving reports of a shooting. When officers arrived, they found 17-year-old David Longfellow gunned down while seated in his vehicle. A girl was also present during the shooting but was not injured, investigators said.
Police reported that an extensive investigation was launched at the time, but no charges were ever filed. The case has remained open for more than 50 years as detectives continue reviewing evidence and seeking new information that could identify those responsible.
State Police say renewed attention on long-term cold cases has helped bring in new leads in past investigations, and they hope the same might occur in Longfellow’s case. Detectives emphasized that even small details—no matter how insignificant they may seem—could help advance the investigation.
The department is urging anyone with information about the shooting, the events leading up to it, or individuals who may have been in the Hermit Road area that morning to come forward. Tips can be submitted anonymously.
Authorities say the goal remains unchanged: bringing answers and justice to Longfellow’s family after more than five decades of uncertainty.
Anyone with information is asked to contact the New Hampshire Cold Case Unit at coldcaseunit@dos.nh.gov or submit a tip using the state’s online form.
