  • Details of Disappearance
    Triska was last seen around 23:45 in a car with an unidentified older male at the Route 88 Drive-In Restaurant in Harmony Township, just north of Ambridge, Pennsylvania on September 19, 1958. She never made it home.

    Police identified a 26-year-old man named Frank Senk as a suspect and found strands of red hair and blood in his car after witnesses said they saw Triska riding in an older man's car shortly after leaving a teen dance on Sept. 19, 1958. Senk explained away the findings by saying the blood was his own and that the hair likely came from his three nieces who, like Triska, were redheads.

    Criminal science available at the time wasn't able to disprove that and Senk was never charged with harming Triska, though he was eventually convicted of the 1961 murder of a 13-year-old girl in Centralia. Senk, a door-to-door knife salesman who was on parole for a Florida morals charge when Triska disappeared, died serving a life sentence in the 1990s.

    Rebecca Triska was never found and was declared dead in 1967.
