INDIANAPOLIS -- The Indiana Supreme Court has set Dec. 11 as the execution date for a man convicted of the 1994 slayings of his estranged wife and two of her relatives in Evansville.

The court said Tuesday that 49-year-old Matthew Eric Wrinkles has exhausted his state and federal appeals and is not entitled to an additional appeal of his death sentence.

Court spokeswoman Kathryn Dolan said Wrinkles still could ask Gov. Mitch Daniels for clemency. The U.S. Supreme Court refused to hear his appeal.

Wrinkles' attorney, Joseph Cleary, had no comment.

Defense attorneys argued that jurors were biased since they could see Wrinkles was wearing a stun belt during his trial.

Wrinkles was convicted of breaking into his brother-in-law's home and killing his wife, her brother and his wife.
