HAYMARKET, Va. (WUSA) -- Prince William County Police are asking the public's help for any information about the 1980 disappearance and homicide of Cynthia Joan Gastelle. DNA samples recently helped identify skeletal remains found in 1982 as belonging to Gastelle, who vanished from her Maryland home as a teenager on April 3, 1980.

The Gastelle family vividly remembers their youngest sibling, and the details about the day she disappeared 32 years ago.
"It's extremely important people come forward so it doesn't happen to anybody else," said Pete Gastelle, a brother of 18-year- old Cindy Gastelle. She had taken a Ride-On bus from her Takoma Park home for a job interview at a Silver Spring deli. The deli called later that night to tell her she got the job, but she never knew it.

Police now believe someone killed her and they're looking for anyone who knew her at the time she went missing.

In 1982, a hiker found her remains in Virginia at the foot of Bull Run Mountain. In 2001, DNA evidence in the case was entered into the national data base. In 2011. DNA from family members was collected in an unrelated case elsewhere, and finally, last month, on May 10th, 2012, a DNA match was found, and using advanced technology, her remains were identified.

When Cynthia Gastelle's remains were found two years after she disappeared, clothes were found, clothes that may have been identified by her family. But the Prince William County Police Department was not aware that she'd gone missing, and they never made contact with Takoma Park Police. Her family spent years hoping she'd come home.

"I was angry at her wondering how she could be so mean to never call. She didn't call because she was dead," said Greg Gastelle, another brother. He says he's grateful police finally found her, but he wishes it hadn't taken so long.

Police are asking for help identifying the man shown wearing sunglasses in the attached photo, whose name may be Mike or Michael. Cindy's family says he was her boyfriend , that she may have broken up with before she vanished. Police think the long-haired young man, who was around 20 years old, was one of the last people who may have seen her alive.

"It's hard to look at a face and wonder, did he killer her? It could've been anybody in the world," said Greg Gastelle. Police are not calling the man a suspect, they're just saying they want to talk to him.

"Our hope lies with you, our friends, people in the community, to please come forward if you know something," said Pete Gastelle. "Cindy, we love you, you're in our hearts , we hope you're at peace."

Her brother and police made a plea for information on Wednesday afternoon during a press conference. If you recognize the man in question, or have any information relating to the case, please contact the Prince William County Police, who are investigating the case as a homicide.
