Authorities believe they have arrested a man who was behind the skeletal remains that were found in South Travis County Sunday afternoon, according to the Travis County Sheriff's Office.

In a statement released Thursday, TCSO said they received a report of a missing man who was believed to have been murdered on July 14. For the next several months, they "followed a number of leads."

Oct Oct. 25, TCSO said they received information indicating that 33-year-old Paul Michael Longoria of Creedmoor had been murdered and that his remains could be found in a wooded area off of Maha Loop Road.

As authorities searched the area Sunday, cadaver dogs found a rolled up tarp underneath a bridge in the 11300 block of Maha Loop Road. Inside the tarp, authorities found the skeletal remains believed to be that of Longoria's.

Samuel Allen McMarion, 19, was arrested on Nov. 2 and charged with murder and tampering with physical evidence. He is currently in the Travis County Jail with a bond set at $300,000.

The Travis County Medical Examiners Office is continuing their investigation. Their final report is expected to be released at least several weeks from now due to the body's extensive decomposition.
