COLLIER COUNTY, Fla. - January will mark 10 years since Macia Wililam's son, Terrance Williams, disappeared.

"The most that I would remember about Terrance, he would come in from work and say, 'Hello mother how was your day?' always."

It's a day she will never forget and has spent her days fighting to find answers.

"If Terrance were here today I would say Terrance I know you don't like everybody getting into your business but I had to do this because I had to find you," said Williams.

Marcia, along with the CUE Center for Missing Persons, and the Coalition of Immokalee workers, held a silent rally at the last place Terrance was seen - Vanderbilt Drive and Immokalee Road. Williams disappeared just a few months after Felipe Santos. Santos was also last seen in North Naples. There's another similarity that the two men share, they were both last seen by the same now-fired Collier Sheriff's deputy, Steve Calkins.

"He's a person of interest in this case yes, both cases," said Detective Kevin O'Neill with the Collier County Sheriff's Office.

Williams said she won't stop until she learns the truth behind her son's disappearance.

"I need to find Terrance for my four grandchildren, I need to find Terrance for me and a lot of people."
