Blood evidence from the rocks would ultimately lead investigators to Krystal's killer, although it would take nearly 20 years and advances in DNA technologies to identify the murderer.

Just five days before a Yale University doctoral researcher was supposed to get married, she suddenly vanished. Video surveillance cameras show Annie Le entering her workplace on the day of her disappearance, but she never left. After her body is discovered in the laboratory basement, investigators find evidence above a ceiling tile, including the perpetrator's bloody clothes. Once suspects are ruled down, DNA evidence points to lab technician Raymond Clark as her killer.

In 2005, suitcases containing human remains wash ashore near the Chesapeake Bay Bridge Tunnel in Virginia. Police release a composite sketch of the victim, who is later identified as Bill McGuire.

In 2009, young mother Heather Strube is brazenly gunned down in a Target parking lot in Snellville, Georgia. The killer was wearing an obvious disguise, though it succeeded in hiding the killer's true identity.

After abducting Wendy Gant, he stabs her several times and slits her throat, but inadvertently leaves her alive. After communicating in writing to a forensic artist, a composite sketch was developed and identified as Corwin. A fingerprint found in Gant's car helps send Corwin to death row, where he is executed in 1998.

In 1987, a young Canadian couple is brutally slain while on a road trip from British Columbia to Seattle, Washington. After their bodies are found, the victims' families begin receiving disturbing letters. The case goes unsolved for more than 30 years, until forensic investigators use personal genomics to help solve the case, ultimately making forensic history.

In 2015, a health-conscious chiropractor from Whitesboro, New York mysteriously dies. After Mary Yoder's autopsy shows the cause of death as colchicine poisoning, the investigation into her suspicious death becomes a homicide case.

In November 2009, a young woman's body is found in Moss Bluff, Louisiana. Tattoos on the victim help to identify her as 19 year-old Sierra Bouzigard, and while the crime initially appears to be sexually motivated, no DNA is recovered from Sierra's rape kit. However, DNA under Sierra's fingernails matches DNA evidence found on a candy wrapper near the scene. After several years with no answers, Blake Russell is identified as a suspect using new DNA technology.

In January 2008, 42-year-old Rhonda Smith was shot as she did temporary work in the office of the Trinity Evangelical Lutheran Church in Springfield Township, Pennsylvania.
