Now, more than four years after Grossman went missing, Taft hasn't heard or seen her daughter.
Not a day goes by that Taft doesn't search for answers. She's afraid time is running out.
"The longer it goes on, the more it's forgotten," said Taft. "Even my details are foggy and I think about it every day."Grossman was last seen at a birthday party in Lockwood in the Spring of 2012.
Taft is convinced that Grossman's boyfriend is responsible for her disappearance, but no definitive evidence or witness statements have led to his arrest.
Despite countless tips and leads over the years, Grossman remains one of 142 faces on Montana's Missing Person's List.
