An 18-year-old man has been arrested on multiple charges after a woman was found dead in his Siloam Springs, Arkansas, home last week.

According to ArkansasOnline, Austin Grammer is facing felony charges of manslaughter, rape, abuse of a corpse and tampering with evidence. Police told KSFM news that Grammer is believed to have raped the dead body.

Grammer was not charged until February 22, following an investigation.

He is currently being held without bond in the Benton County Jail until his April 3 arraignment.
