Six people -- including five volunteer firefighters -- face criminal charges in Ellis County after a firefighter trainee reported last week that he'd been sexually penetrated with a sausage in January.

Authorities arrested Keith Wisakowsky, 26; Casey Stafford, 30; Alec Miller, 28; Blake Tucker, 19; and Preston Peyrot on sexual assault charges. Texas Rangers allege Brittany Leanne Parten, 23, illegally filmed the assault on her phone. The video features yelling and laughing during the incident, the Rangers say.

According to the Rangers, who were called in by Ellis County to investigate after the trainee came forward on March 31, the men committing the assault initially planned on using a broomstick before deciding a link of chorizo in the fridge was a better choice.

Wisakowsky retrieved the sausage, and the trainee was bent over the couch while Tucker and Stafford held him down and the sausage was inserted into his anus, the Rangers say. Then Wisakowsky cut the sausage out of the package and attempted to reinsert it, but the sausage broke up.

The trainee told the Rangers he was then released and he crawled into the nearby restroom with "smashed up sausage still between his butt cheeks." He removed the sausage, threw up and took a shower to clean up. While he was showering, he says, someone took his clothes from the restroom. He came out of the restroom in a towel to look for his clothes. When he did, he says, Tucker took his towel. The man covered his genitals with his hands and ran to his truck to get some shorts, he says.
