David Braley was last seen on a chilly Friday night in November 1989 at what used to be called Take Five Music Hall near the intersection of Garvins Falls Road and Manchester Street.

Braley’s body was found in the Merrimack River four months later on March 18, 1990.

Initially, police did not suspect foul play in his disappearance, according to reporting in the Monitor, but his death has since been investigated as suspicious

Sunday was the 35th anniversary since Braley went missing and city police and the New Hampshire Attorney General’s Office have renewed their call for information, especially from witnesses, that may help them find the truth behind what happened.

“Please be that person to come forward,” his family wrote in a statement, adding that they would be “forever grateful for any information to help bring them peace, closure, and comfort.”

Braley, 21, of Belmont, was last seen Nov. 10, 1989 near the Take Five night club that later went by the names The Music Hall and Shenanigans. 

Investigators believe Braley was “violently assaulted” before his body was thrown in the river. They also believe potential witnesses exist who have not yet come forward, who may have “been afraid to speak with the police at the time or were concerned that police would not believe them because of certain stigmas,” according to the Cold Case Unit of the attorney general’s office. 

Michael Garrity, a spokesman for the Attorney General’s Office, said that “some potential nightclub patrons or members of the public, in general, might have felt that police would not believe them because of their involvement in criminal conduct, social drug or alcohol use, immigration status, or sexual orientation.”

Braley was a 1986 graduate of the Maine Central Institute in Pittsfield, according to his obituary. He worked as an alignment specialist for a Goodyear service center in Concord, volunteered at the McKerley Health Care Center in Laconia and helped create a Halloween display at the Belmont Mall. Born in Attleboro, Mass., he also lived in Norton, Mass. before moving to Belmont around 1986, where his parents, brother and sister were also living when he died. 

“During the initial stages of the investigation, several conflicting and contradictory stories concerning David’s disappearance circulated in the community,” according to a statement from the Attorney General’s Office. “Investigators are steadfast in their efforts to bring the truth of what happened on that November night to light.”

For a little over a year, police have been re-examining Braley’s disappearance, and hope that advancements in forensic technology will help uncover new information. 

His relatives and investigators have urged anyone with information to come forward. 

“If you know what happened or have any information about this investigation — no matter how trivial it may seem to you — we ask that you please come forward,” investigators said. “Even the smallest observation could provide a crucial piece of the puzzle.” 

Those with information can contact the Concord Police Department at (603) 225-8600, or the Concord Regional Crimeline at (603)226-3100, or the New Hampshire State Police Cold Case Unit tip line at (800) 525-5555 or via email at coldcaseunit@dos.nh.gov.
