Enlarged heart suspected factor in death of inmate held in slaying of 2 Miss. police officers

Mississippi officials say an enlarged heart is a likely factor in the death of a 30-year-old inmate jailed since last May in the slayings of two Hattiesburg police officers

Forrest County Coroner Butch Benedict said there were no signs of trauma on the body of Marvin Banks, who died Friday.

Warren Strain, of the Mississippi Bureau of Investigation, said the initial autopsy shows an enlarged heart and scar tissue on the heart. But a cause of death won't be determined until other tests are completed. Results will likely take weeks.

Nick Calico of the Forrest County Sheriff's Department said Banks was found unresponsive in his cell Friday evening.

Banks was charged with capital murder in the shooting deaths of officers Benjamin Deen and Liquori Tate.
