They were kids in high school when their friend Julie Ferguson was murdered, and 20 years later it still weighs heavily on their minds.

17-year-old Julie Ferguson was last seen at a shopping center in Greenbelt, waiting for a ride home from friends.

Her body was found the next morning at an athletic field 3 miles away. That field is now the Julie Ferguson shelter and play area and it’s where family and friends gathered to remember her life and hopefully find justice for her death 20 years later.

“At 5:15 this morning 20-years-ago Julie Ferguson was found brutally murdered right where we are today. Her throat was viciously cut and she was strangled to death. No one deserves, let alone Julie, to die that way,” said Detective Bernard Nelson, Prince George’s County Police.

Police say a witness reported seeing Julie Ferguson talking with three people in a car the night she was killed. Those three people have never been found.
