Jessica Frederick, 27, was found murdered on December 5, 1998, in an industrial area of Pittsburg, California. Her body was discovered near a wrecking yard on Harbor Street; she had been stabbed. Frederick was one of several women killed in Pittsburg during late 1998 and early 1999, a string of homicides investigators at one point suspected might be linked to a single offender, though that link was never confirmed.

Her boyfriend, Mohammed Niaz, was briefly arrested after blood traces were found in his apartment but was cleared when DNA testing excluded him. The case remains unsolved and is still considered part of the larger murder mystery that puzzled investigators at the time.

Did anyone who knew Jessica or who worked in the Harbor Street area in 1998–1999 see or hear anything that could help reopen leads?
