Summary based on the NamUs case record (MP118665) and 3 other sources
Robert Langlais, a 44-year-old man, was last seen on March 11, 1998, in Rochester, New Hampshire. On that day, his car was found abandoned on the Piscataqua River Bridge, still running but with no sign of Robert. He has not been heard from since that day, and his disappearance is considered an endangered missing person case. Authorities have no record of any distinguishing physical marks or features, nor information on what he was wearing when he disappeared. Investigators have not been able to determine the circumstances that led to his disappearance, and he remains missing to this day.

The case is being handled by the Rochester Police Department, which continues to seek any information that might help locate Robert. Unfortunately, there were no dental, fingerprint, or DNA records available to aid in the identification process, which has made the investigation more challenging. His case has also been registered in the NamUs national database, which keeps a record of missing individuals in hopes of finding new leads through public or forensic contributions.

The New Hampshire State Police are involved in investigating cold cases like Robert’s, and they encourage anyone with information to reach out. They often reexamine evidence using modern forensic methods such as DNA analysis, and also conduct public outreach in an attempt to generate new leads. Despite the lack of significant updates in the case, Robert's disappearance remains open, and authorities hope that advances in technology or new information from the community might someday help solve it.

Robert’s case highlights the ongoing challenges of missing person investigations, especially those that happened decades ago. Community involvement and public awareness continue to be vital tools in efforts to find answers for his family and loved ones. If you have any information regarding Robert Langlais or other missing persons from New Hampshire, authorities encourage you to contact the Rochester Police Department or the New Hampshire State Police to assist in these investigations.
