A DNA sample match has led police to arrest a registered sex offender for raping a woman near the mouth of Ogden Canyon in May.

The 45-year-old Ogden man, James F. Cox, was arraigned this week on felony rape charges, said Ogden Police Detective Tim Scott.

On May 25, a woman was walking near the canyon when a white truck pulled over. A man got out, grabbed her, and raped her, Scott said.

The Ogden police sent a DNA sample to the state crime lab. The analysis was completed in November, and the sample matched one filed in a national database after a sexual assault in Nevada, Scott said. The match was then confirmed with a new sample, and the man was arrested on Jan. 23.

Scott said the lag time between the incident and the arrest was typical -- lab results for DNA samples often take months to confirm through the state crime lab.
