Brian Perlish was 30 when he was last seen leaving his Philadelphia home on November 23, 1997. He is described as a white male, brown hair, brown eyes, 5 feet 6 inches and about 140 pounds. After that day he was never seen or heard from again.

Earlier notes in local coverage identified him as a music major at Temple University and mentioned a school project that referenced mathematical principles of pizza sizes. The Philadelphia Police Department is handling the investigation, which remains open but cold. Little has been released about his clothing or state of mind the day he disappeared.

If anyone knew Brian, lived near him, or has information about his movements around November 23, 1997, please share what might help investigators or his family.
