Tom Capano, a once wealthy and politically connected attorney serving life in prison for killing a mistress in 1996, has been found dead in his prison cell.

State officials said the 61-year-old Capano, who spent time on death row before his death sentence was overturned, was found unresponsive Friday morning in his cell at the state prison in Smyrna. He was pronounced dead shortly after noon.

Capano was convicted of shooting his mistress, Ann Marie Fahey, after she decided to end an affair with him.

Fahey was the scheduling secretary to then-Gov. Tom Carper, now Delaware's senior U.S. senator.
