An inmate at the U.S. Medical Center for Federal Prisoners in Springfield is dead and now authorities are investigating his death as a possible homicide.

Victor Castro-Rodriquez, 51, who was incarcerated "because he was dangerous due to mental illness" was found unresponsive in his cell Tuesday evening. After failed attempts to resuscitate him, Castro-Rodriquez was pronounced dead about 8:40 p.m.

Warden Marty Anderson says that Castro-Rodriquez, who was from southern Florida and has been incarcerated at the Fed Med since 2002, did not have a cell mate.

Anderson says that the FBI is in charge of investigating the inmate death, "because they have law enforcement jurisdiction over federal prisons."
