Michael Showers, who played New Orleans homicide Captain John Guidry on the HBO drama, was found dead in the Mississippi River Wednesday morning. The actor was 45 years old.

A steamboat captain saw Guidry's body floating in the river near New Orleans' French Quarter and called the authorities. The police told the New Orleans Times-Picayunehis body had been in the water for nearly two days. No official cause of death has yet been determined.

The death is eerily reminiscent of on-screen suicide that occurred in Season 1 of the show, when John Goodman's character Creighton Bernette killed himself by jumping off a steamboat into the Mississippi.

In the show, Showers' Capt. Guidry character butted heads with David Morse's Lt. Terry Colson over whether NOPD officers should be investigated for violence in the aftermath of Katrina.

Guidry has also appeared on 'The Vampire Diaries' and 'Breaking Bad.' His film credits include 'The Tree of Life,' 'Traffic,' 'I Love You Phillip Morris,' and 'Colombiana.
