Police in Lancaster have a new clue in a nearly 45-year-old cold case.
Images in the video above show what the killer may have looked like at age 25 --- and then at age 65.
WGAL reported that a company produced the images based on the DNA left behind after 19-year-old Lindy Biechler was sexually assaulted and stabbed to death in her apartment in Lancaster County back in 1975.
Lindy and Phil Biechler had been married just more than a year.

Phil Biechler said the only person he thinks the images could resemble has already been cleared as a suspect, WGAL reported. Phil Biechler has also been cleared.
