The unsolved death of a teenager in 1977 haunted students and staff at Honolulu's McKinley High School for nearly half a century. But last week, police used advances in DNA

Before Dawn Momohara was killed, she got a call from an unknown male and told her mother she was going to a shopping center. That was the last time her mom saw her, police said.

Dawn Momohara was 16 years old when her body was found on the second floor of McKinley High School in Honolulu in 1977. For decades, detectives had failed to identify a suspect in the murder case but now, thanks to a breakthrough in DNA technology, they have arrested a former classmate, police confirmed.
