He was also believed to have been seen on Wednesday on camera in the 13300-block of Old Western Avenue in Blue Island. He was last seen wearing a black jacket, red shirt, and dark pants.
The 59-year-old is described to be 5-feet, 8-inches tall, weighing about 170 pounds.
His family gathered to form a search party Friday at 3359 W. 115th St. in Merrionette Park.
The missing person's case is being handled by the Chicago Police Department. Anyone with information is urged to contact Chicago police, or call 911.
Loved ones are hoping he's found safe soon.
"We are not paying attention to what day it is or the holidays...or anything," his daughter Wendy Davis said. "We've just been super focused and putting 100% of our energy into every possible lead we get."
The family has been searching for him around the clock. On Friday, they gathered at 115 Bourbon Street in Merrionette Park to form a search party and pass out flyers. The location is a place where Davis has been working for years.
"It's really disheartening," 115 Bourbon Street general manager Jon Haenke said. "He's been part of our family for 26 years going on, so we're just trying to get him out of the cold weather."
The family says they still have questions over the car crash that took place about 1 mile away, but their focus right now is finding Davis.
"He was only here for a couple of hours on late Monday night, going into Tuesday morning. He was here between I think around 11:30 to 1 a.m. going into Tuesday morning," Wendy Davis said. "A couple of hours before he went missing. He was involved in a car accident, and we believe that he might have gotten injured with a head injury has based off his movements and everything in all this videos he seems a little disoriented."
Officers from the Merrionette Park Police Department provided family members with moral support as the search resumed across neighboring towns.
"Any information you do get communicate to Chicago police right away," Merrionette Park Police Chief Mathew Ramirez said.
The family hopes videos and images of the last time he was seen will keep neighbors informed and alert, in case he is spotted again.
