Slidell police discovered blood, human bones and candles arranged in what appeared to be a makeshift altar during a search Tuesday and are searching for the man who lived there, a spokesman said Thursday.

A tip led police to the home on Woodcrest Drive, where officers found human skulls, other human bones, animal bones and dried blood in a cast iron bowl surrounded by candles and “other ritualistic materials,” Sgt. Daniel Seuzeneau said in a news release.

The resident, Joshua Roques, may have been sacrificing animals on the altar, and detectives believe the human bones were stolen from graves and do not indicate a homicide, Seuzeneau said. The dried blood appeared to be animal blood, he said.

Roques rented the house and was not home when a search warrant was served. He is believed to be hiding in New Orleans and may be making plans to leave the state, Seuzeneau said.

Police asked anyone who knows where Roques is asked to call the Slidell Police Department at (985) 643-3131. He may be driving a silver Infiniti G35 sedan.

Seuzeneau said Roques is wanted on several counts, including interring or cremating human remains, unlawful disposing of remains, opening graves, mutilating or disinterring human remains, possession of cocaine and possession of drug paraphernalia.

The Coroner’s Office took possession of the bones and confirmed that some were human and others came from a dog and other animals. DNA has been sent to the Louisiana State Anthropology Lab to help identify the bones.

The case comes on the heels of a similar story in New Orleans, where a self-described witch was accused of offering human bones for sale on Facebook.
