On Monday, a vigil for James was held at Katz Plaza in Pittsburgh.
"There’s no harder thing in life than this. Absolutely nothing. But we're doing the best we can. Keeping our heads up, trying to find our son," Jeff James, Dakota’s father, said at the vigil.
James was last seen Jan. 25 in downtown Pittsburgh, walking through the cultural district.
James' family is from Maryland, but has come to Pittsburgh every week to look for him.
"This is an area I've never been to in my life, so I certainly need the help. And for them to come out and volunteer their time and their knowledge, it's just extremely helpful for us," his father said.
A national organization has also joined in the search for the missing Duquesne University graduate student.
The nonprofit group Bring Our Missing Home is now working with the James family. The group is accepting sign-ups for anyone who wants to help with the search.
