AFFIDAVIT: Accused San Marcos 'serial rapist' faces 6 felonies in 3 assaults, 1 burglary

SAN MARCOS (KXAN) — New information from court affidavits reveal a man described by police as a "serial rapist" in San Marcos is accused of sexually assaulting two roommates for hours at gunpoint in their apartment. 

Tyshane Vris Thomas, 20, was questioned Tuesday and allegedly confessed to three sexual assaults and one burglary, according to the San Marcos Police Department. He attended Texas State University in fall 2018 and studied criminal justice, police said.

On May 2, the two roommates returned to their apartment at The Retreat on Craddock Avenue after class at Texas State University, according to documents filed in court. The victims told investigators when they got home, one went to the kitchen and the other when to her room to study.

Thomas allegedly emerged from a bedroom where he had been hiding and led the girl in the kitchen to the bedroom where the other girl was. Thomas allegedly used zip ties and blindfolds on the victims during the attack. 

One of the victims told police she tried to wrestle the gun away from Thomas several times but she wasn't able to and Thomas would choke her until she almost passed out. The victims said the alleged assault went on for hours.

Thomas allegedly ordered the victims to take a shower after the assault and while they were in the bathroom, the victims told police they could hear him talking on the phone. They claimed he repeatedly said "Yes, Sir" to the unknown person on the other end. He also allegedly told the person on the other line that he was at the girls' apartment when them. 

The victims called for help as soon as Thomas left the apartment. Based on the suspect description, police released a sketch of the suspect the next day in an effort to identify the attacker.

On Tuesday, May 7, San Marcos police officers were called to investigate a suspicious object at the Sanctuary Lofts Apartments on the 300 block of North Street. 

Inside the backpack, they found "a black hooded sweatshirt, a black mask, a BB pistol made to look like a real handgun, and several items of women’s clothing." Officers later determined the objects in the backpack were consistent with the alleged sexual assault on May 2.

Thomas' name was written on the backpack. They also noticed he matched the description of a suspect in a sexual assault on April 24 and a burglary on April 30, both at the Cottages of San Marcos apartment complex, also located on Craddock Avenue. They obtained a warrant to search his Sanctuary Lofts Apartment. 

"That search yielded the discovery of other items believed to be tied to the prior assaults including duct tape, zip ties and personal lubricant," San Marcos police said.

Thomas is being held at Hays County Jail. The charges he faces include:

  • Three counts of first-degree felony sexual assault
  • Two counts of first-degree felony burglary of a home with the intent to commit sexual assault
  • Third-degree felony burglary of a home with other intentions. 

Staying Safe

“I can’t over-emphasize enough how important it is that citizens who seen things that just don’t seem right especially when we are facing a threat like this, that they call us and that’s exactly what they did,” said San Marcos Police Chief Chase Stapp.

Texas State senior Sara Singer lives near where one of the attacks happened. 

"I’m thankful and glad, but I don’t feel completely calm by (the arrest)," she said. "I worry that maybe someone will follow the pattern — it wasn’t just this one guy. There have been other assaults too, but I am glad that police caught him.”

If you or someone you know is a victim of sexual assault, notify authorities. For more help, you can call the National Sexual Assault Hotline at 1-800-656-4673. For more resources click here
