VIDEO: This week marks 20 years since a prank at a student apartment complex turned deadly in Greensboro.
Janet Danahey, a UNCG student, set outside items on fire at a Campus Walk apartment. She said she was trying to get back at an ex-boyfriend. The fire spread to the entire building.
Four people, sisters Rachel and Donna Llewellyn, Elizabeth Harris and Ryan Bek, died, and many others were injured. It was the deadliest fire in Greensboro history when it happened. David Douglas was the chief fire investigator when it happened. He said he thinks of it every year.
"I feel sad for the people who lost their kids," Douglas said. "I obviously always think about that but also for all the other people impacted, as a firefighter, how fire traumatizes people."
Danahey was sentenced to life in prison without parole.
