Roland Matthew Sheppard, 34, of San Angelo, Texas, was killed in what local authorities describe as an exceptionally violent homicide. Police opened an investigation on June 24, 2026, after an anonymous tip about a possible homicide on the north side of the city led detectives to a dumpster in the 600 block of Baker Street. Although the dumpster had already been emptied, investigators traced the commercial trash truck and recovered fresh, bloody clothing and a large piece of blood-stained carpet.

A search warrant for the Parker Street residence where Sheppard lived with his 31-year-old live-in partner, Audrey Troncoso, followed. Investigators say evidence indicated a homicide occurred on June 23. Portions of Sheppard’s body were later recovered from the Republic Services landfill. Troncoso was interviewed by the Criminal Investigations Division and confessed to shooting Sheppard in the face, stabbing him multiple times, and dismembering his body. Troncoso’s father, Mario Valdes-Troncoso, was arrested and charged with tampering with or fabricating physical evidence for allegedly assisting in concealing and disposing of the remains.

Troncoso is being held in the Tom Green County Jail on a $2 million bond and is charged with murder. No motive has been released as the investigation continues. Did anyone in San Angelo know Sheppard or observe unusual activity around the Parker Street or Baker Street areas in late June?
