Kellar always wanted to be a singer in a rock and roll band. He would hitchhike to California, Colorado and Florida, exploring the United States and chasing that dream. The last time he left, he never came back.
According to family members he wasn't acting like himself in the months prior to his disappearance. He was depressed and also had other problems that were hard for him to handle and may have been using drugs. Kellar's family reported him missing in 1992, two years after he left on his last cross-country trip. They assumed he would be back. Muscatine Police took the report but didn’t find evidence of a crime. Because there was no indication of foul play in the disappearance of Kellar, the investigation concluded that he left the area voluntarily.
Kellar's family believes he is residing in another state probably Colorado, California, New York or Florida. They have not had any contact with him and are concerned as a result of this. (Information retrieved from NamUs.gov)
