ST. AUGUSTINE, Fla. -- "We're not going to give up until we find Barbara."

That's what St. Johns County Sheriff David Shoar said during a news conference on Friday as the search for 67-year-old Barbara Parchem continues. Parchem has now missing three weeks.

Friends and co-workers from the Village Inn in St. Augustine have been passing out flyers as far as the Jacksonville International Airport in hopes of finding her.

The booths and tables normally full of Parchem's regular customers are empty. Her section is now a memorial for the missing waitress who has spent 20 years serving up a smile.

"She's a wonderful person, sweetheart and she'd do anything for anybody and she's terribly missed," said co-worker Terri Falandys.

Shoar said Parchem is a woman of routine, adding it is unusual for her not to show up for work. He said Friday he suspects foul play, as three weeks have passed since she has disappeared.

Detectives have done multiple searches near Parchem's house in Vermont Heights area with off-road vehicles and air units. They're now enlisting the help of Equusearch a Texas-based search and rescue organization.

"I knew her personally where she worked and she was a lovely woman, so we're going to bring this case to closure," Shoar said.

There are no persons of interest at this time and the Sheriff's Office staying mum on the locations for their continued search
in an effort to locate additional evidence and close a case that affected everyone from her family to her regular customers.

"Hard. They're still asking questions every time they come in if we've heard anything yet," Falandys said.

Parchem is 5-foot-3 and weighs 100 lbs. She has short brown hair with blonde highlights. She was last seen on April 5 wearing a dark shirt and pants and a gray hoodie driving a red 2005 Nissan Pathfinder in the Molasses Junction area.

Parchem's Village Inn co-workers are collecting donations to put up a billboard along County Road 207 to help generate more leads. If you have any information, call SJSO at (904) 209-2193.
