Search efforts have included K9s, helicopters, drones, boats, and foot patrol, the sheriff's office said. There have been some tips but none that have panned out, Allen said.

\"Unfortunately with all the efforts that they've been putting out, from literally air, land and water, we have not made contact with him at this point,\" Allen told ABC News on Tuesday.

Kotowski's information has been entered into national databases and sent out to agencies statewide, the sheriff's office said.

His family said they are not leaving Hilton Head Island without him while pleading for people to help.

“We just want him to come home,” Jackie Kotowski told WJCL. “We need help from anybody who can assist us in finding him.”

Zak Kotowski also had a message for his dad: \"We love you. Come home, we just want you home.\"

Kotowski was last seen wearing a gray Coors Light T-shirt, dark-colored shorts and no shoes, as captured on a Ring camera footage shared by the Beaufort County Sheriff's Office. He is approximately 6 feet tall and weighs around 200 pounds, with short brown hair and brown eyes and a thick Boston accent.

The Beaufort County Sheriff's Office has asked residents to review their cameras and check their property for any signs of Kotowski. Anyone with information is asked to call the sheriff's office at 843-524-2777.
