Christina Marie Martinez was 15 when she vanished from Phoenix, Arizona, in spring 1997. On May 3 she was reportedly heading to a local laundromat and never returned. A week later remains of a young female were found near Florence, Arizona; for years the victim remained unidentified.

In June 2010 forensic analysis finally identified Jane Doe as Christina Marie Martinez, turning a cold case into an active homicide investigation. Investigators focused on Craig Leslie Jacobsen, a man already imprisoned in Nevada for the killing of a 20-year-old woman named Ginger Rios. Jacobsen owned a Spy Craft store in Phoenix near the laundromat where Christina was headed and a similar Las Vegas store tied to Rios.

Maricopa County charged Jacobsen with Christina’s murder in 2014; he was extradited from Nevada to Arizona in 2015. Subsequent proceedings were delayed amid questions about Jacobsen’s mental competency, with a judge at one point finding he was feigning incompetence. Are there readers who knew Christina or who recall seeing her near that laundromat in 1997?
