abbyPD24(NEWS 1130)  A man has been arrested in connection with a sexual assault that happened 16 years ago.  On August 7, 1999, a woman was walking to her car after leaving an outdoor party on Ward Road near Sumas Mountain Road when she was sexually assaulted, choked, and threatened with death.  Police say the case went unsolved until December, 2013, when investigators sent previously seized clothing for DNA analysis. In early 2014, a suspect was identified through the DNA profile.  Last month, James Allen Redden was charged with sexual assault, unlawful confinement, and uttering threats. The 48-year-old man was living on Vancouver Island.
