The deaths of Daniel and Stephanie Menard appear to have been caused by “blunt force trauma” to the head, Mara Rodriguez from the San Bernardino County Sheriff-Coroner Department said. Nearly a week after being reported missing, the remains of the Menards were found under their neighbor’s house at the Olive Dell ranch in Redlands.

The Redlands couple who went missing last month before they were found dead at a nudist resort died from blunt force trauma to the head, according to San Bernardino County officials. Earlier this month, 62-year-old Michael Royce Sparks, pleaded not guilty to two charges of murder in the killings of his neighbors, Daniel and Stephanie Menard.

The San Bernardino County coroner confirmed a Redlands couple's cause of death on Monday, nearly two weeks after their remains were found underneath their neighbor's home.
