Austin Boutain, the suspect in a fatal carjacking case in Utah, is one of two people who are described as persons of interest in the case.

“The Salt Lake Police Department was conducting an investigating a shooting on the campus of University of Utah, and through that investigation they found some nexus to this RV in Colorado, and so we came to do the welfare check based on that,” Golden police Capt. Joe Harvey said. “The rest of those facts are still under investigation and a little cloudy for us in terms of how it was connected to Colorado.”

Police in Salt Lake City contacted Golden police early Tuesday morning with a request that a welfare check be done on an RV trailer located in the Clear Creek RV Park. The park is on the west side of downtown at the end of 10th Street.

Investigators found the man’s body in the RV. They said the man appeared to have been dead for a few days and that he appeared to have died under suspicious circumstances. He is not being identified, but police said he had been staying in the RV park.

Boutain was arrested after an extensive manhunt following the Monday night carjacking. The victim in that case is ChenWei Guo, a 23-year-old University of Utah student from China.

Golden police said the 63-year-old’s pickup truck, which had Colorado plates, is the one police in Utah initially said Boutain might be in.

In addition to Boutain, 24, Kathleen Boutain, 23, is also being described as a person of interest in the Golden case. She is in custody in Utah.
