Illinois Department of Corrections spokeswoman Sharyn Elman had said Thursday that Coleman was moved to an out-of-state maximum security prison under the Interstate Compact Agreement, which allows for the transfer of convicts in high-profile cases for safety and security reasons. She would not disclose his new location.
A Dodge prison staffer said a man with the same name and age as Coleman had entered the prison Wednesday.
Chris Coleman is serving his life sentence in a Wisconsin prison.
Ron Coleman said his family were not told anything about his son's transfer.
No specific incident or threat had triggered the move, Elman had said.
Coleman, 34, had been at the Pontiac Correctional Center since being convicted in May for three counts of first-degree murder for the slayings of his wife, Sheri Coleman, 31, and their two sons, Garett, 11, and Gavin, 9. Prosecutors said Coleman killed his family, which lived in Columbia, to start a new life with his mistress in Florida.
Enrico Mirabelli, a relative of Sheri Coleman, said the family didn't really care where Christopher Coleman was as long he was locked up -- the family didn't plan to send him any "cookies."
Coleman was sentenced to life in prison.
