LOUISVILLE, Ky. (WDRB) -- The search continued Wednesday for Andrea Knabel, the missing Louisville mother last seen nearly a month ago in the Audubon Park area.

Tips are taking investigators miles from where she was last seen.

More than a dozen people, including strangers, are showing up to help look for Knabel.

Searches began Wednesday at 5:30 a.m., after a tip led investigators to Iroquois Park. Family, friends, and even strangers were there looking for Knabel.

"She's always been there for people and I want people to be there for her," said Nancy Schaefer Smith, one of Knabel's closest friends and founder of Missing in America, a group dedicated to finding missing people. It's a group Knabel actively volunteers with.

"It's hard separating the emotional from the professional," Schaefer Smith said.

Due to Knabel's involvement with Missing in America, those searching for her don't believe she'd willingly go this long without contacting someone and fear she may be in danger.

"We just want her to come home," added Schaefer Smith. "She knows how this is on families, and she knows what it takes in an investigation, and conducting searches and stuff like that ... and how much of an emotional toll it takes on people."

Knabel's friends and family say they won't stop looking for her until she's found.

"There's many that will not stop searching," her father, Michael Knabel, said.

"If anyone has Andrea, please let her go," said Schaefer Smith. 

Investigators and Andrea's family said if she did disappear willingly, they want her to contact them and let them know she's safe.

"You are so loved," said Schaefer Smith. "You're not in any trouble. There's not going to be any consequences."

Anyone with any information on Knabel's location is asked to call police at (502) 574-LMPD or investigators at 502-618-9337. There is a $1,000 reward for information that leads to Knabel. Separate rewards are also being offered for credible pictures of her.
