Summary based on the NamUs case record (MP7919) and 10 other sources
In the autumn of 1986, fifteen-year-old Tamara 'Tammy' Dawn Porrin was navigating the complexities of adolescence in her hometown of DuBois, Pennsylvania. An eighth-grader at DuBois Junior High School, she was known to have a strained relationship with her parents, often leading to arguments and instances of running away. Tamara also struggled with school, marked by habitual truancy. On the evening of November 22, 1986, the day before her sixteenth birthday, Tamara was seen for the last time. She vanished without a trace, leaving her family and community with decades of unanswered questions.

Due to her history of running away, Tamara's disappearance was initially not treated as a high-risk case. It is unclear when exactly she was first officially reported missing, with some reports indicating she was entered into a runaway database in 1986, though it's uncertain if this was connected to her final disappearance. Other sources suggest a formal report wasn't filed until years later, possibly as late as 1994. This delay in a formal investigation meant that crucial early leads may have been lost. School records show she was withdrawn due to lack of attendance on December 9, 1986, after officials made unsuccessful attempts to locate her at her home. The lack of immediate and widespread media attention at the time is evident from the absence of any news reports about her disappearance in archived local newspapers.

As years turned into decades with no contact or sightings, the likelihood that Tamara had simply run away and started a new life grew increasingly slim. The extended period without any communication led investigators to suspect that she had met with foul play. The case is now classified as an endangered missing person, and the Pennsylvania State Police are the lead investigating agency. Despite the passage of time, law enforcement continues to seek information from the public that might shed light on what happened to Tamara Porrin on that November evening. The circumstances surrounding her disappearance remain unknown, and her case is an unsolved and deeply felt loss for her loved ones.
