Homicide Lt. Ray Spencer said during a Wednesday news conference that new DNA technology, funded by a donor named Justin Woo, was used to identify Darren Roy Marchand as the man suspected of strangling teen Stephanie Issacson.

Stephanie was reported missing on June 1, 1989. She left home that morning to walk to class at Eldorado High School but never arrived and never came home, police said.
Marchand, of Las Vegas, died by suicide in 1995, police said.
