On Monday, Calvin, family members and a neighborhood crime fighting group took to the streets again to search for Joyce. They handed out flyers to drivers.
Calvin said his wife has Dementia and is currently without her medication. He is offering a $1,000 reward for her safe return.
"I won't stop. It's hard to stop. I can't stop, can't sleep. So how will I stop just looking for her? When I am at home I don't feel comfortable knowing she is out here lost somewhere," Calvin said.
Joyce is 4 feet 10 inches tall. She weighs about 90 pounds. She was last seen wearing a red coat and khaki pants. The couple's home is near Grand River Avenue and Lahser Road, where she was last seen.
Joyce Friday has been missing since Dec. 1, 2012.
