HARTFORD, Conn. — A Connecticut Roman Catholic priest who ran a methamphetamine ring has been sent back to prison for nine months for failing another drug test while on supervised release.

Kevin Wallin asked a federal judge in Hartford on Thursday to continue his supervised release so he could begin long-term residential treatment for substance abuse.

But Judge Alfred Covello sent Wallin back to prison. Covello warned Wallin earlier this year that he faced more prison time if he failed another drug test.

Wallin resigned as a pastor in the Bridgeport diocese in 2011, and proceedings are underway to permanently remove him from the priesthood. He was dubbed “Mosignor Meth” in some media reports.

He was sentenced to more than five years in prison in May 2015 for selling meth and freed on supervised release in November 2016.
