Stephen Anthony Taylor confessed to killing Sandra Graves in text messages to family and friends.

DeFUNIAK SPRINGS — A Walton County grand jury returned a murder indictment Wednesday for Stephen Anthony Taylor, the 36-year-old man who was arrested for allegedly killing Sandra Graves in June. 

The jury indicted Taylor on one count of first-degree premeditated murder and/or felony murder, one count of burglary to a dwelling while armed with a dangerous weapon, one count of grand theft and one count of grand theft auto, according to the State Attorney's Office. 

Graves, 38, was found dead June 26 in her home in DeFuniak Springs from an apparent stabbing. 

Taylor and Graves worked together at the Beef O'Brady's restaurant on U.S. Highway 331 and had been in a past relationship, according to authorities. Taylor confessed to killing Graves in text messages to family and friends. In a statement to authorities, he said he began plotting to kill Graves after she told him she "didn't need his help" dealing with a difficult customer at the restaurant. 

Taylor broke into Graves' home June 25 and waited until she got home before he allegedly stabbed her in the neck. 

Taylor then took her car "joy riding" and waited 24 hours before informing relatives what he had done. A relative alerted police and he was arrested at a Burger King in DeFuniak Springs about 8 p.m. June 26.
