WALHALLA, S.C. - A murder charge against a Walhalla man has been downgraded after his girlfriend's death was ruled an overdose, not strangulation.

Prosecutor Chrissy Adams said in a news release Friday that 30-year-old Caleb Nathanael Linart has now been charged with attempted murder.

Linart was arrested last month after the body of 27-year-old Alana Concetta Carpenter was found at a house in Walhalla. Authorities originally thought she had died of an overdose of alcohol and prescription drugs. But an autopsy showed she had been strangled.

On Friday, Adams said that, based on toxicology results, Carpenter's death has been ruled an overdose. Court records listed no attorney for Linart.
