Matthew Schellinkhout, Thomas' only child who lives in Lafayette, Indiana, said his mom was great at cheering people up. He added that his two children called her "Grandma Barbie," and that she was given the nickname because of her beauty.
"Mom liked Collies and Himalayan cats, a very outgoing personality — loved to dance and cook," he said.
"My mother and I were close. ... (We) spoke on the phone often (and) she loved my children, Christopher,13, and Natalie, 11. ... I wish my children and I lived out there. (Her disappearance) would not have happened," he added.
Schellinkhout explained that Thomas had previously been married to his father and then 14 years ago was remarried to Robert Thomas.
Cindy Bachman, a sheriff's spokeswoman, said that investigators were looking into all leads.
The agency's Specialized Investigations Division has assumed the investigation into Thomas' disappearance, according to Bachman. The department's website states that the Specialized Investigations Division is composed of homicide detail, crimes against children and technology crimes.
