Headline Goes Here

ST. PETERSBURG, Fla - A twice convicted murderer who has lived on Florida's death row for more than three decades is scheduled for execution this week.

If 65-year-old Robert Brian Waterhouse dies by lethal injection on Wednesday, he will have been on death row longer than any of the 276 people eventually executed by the state. Only 18 of the current 395 inmates on death row have been there longer.

Waterhouse was sentenced in September 1980 for the killing of Deborah Kammerer of St. Petersburg. She had been raped, beaten and left to drown in the tide of Tampa Bay. He was on parole from New York for murdering a 77-year-old woman during a 1966 burglary.

Waterhouse's execution is set for 6 p.m. Wednesday.
