DETROIT (AP) — An inmate at a federal detention center in Michigan has been sentenced to 28 additional years in prison in the killing of a fellow inmate convicted of leading a child pornography ring.

Jason Dale Kechego of Detroit was one of three men accused of murdering 40-year-old Christian Maire at the Milan Correctional Facility in January 2019.

Kechego, 41, was convicted of second-degree murder after a jury trial. A federal judge in Detroit sentenced him Tuesday to a 28-year sentence that will run consecutive with the 10-year sentence he’s already serving for possession of a stolen firearm, federal prosecutors said.

Officials said Kechego and Adam Taylor Wright, 42, repeatedly kicked and stomped Maire in the head.
