Casper Man Who Bit Deputy’s Finger Off, Barks Like Dog Gets 28-35 Years In Prison

A 40-year-old Casper man who bit the tip of a deputy’s finger off and barked like a dog at a judge was sentenced Friday to 28 to 35 years in prison. Andrew Beau Barrett entered a plea deal in January that saw two charges dropped, with the prosecution agreeing not to ask for more than 35 years on an aggravated assault and battery charge plus being an habitual criminal. He also received four to five years for possession of a controlled substance, third or more offense, to be served concurrently.

Assistant District Attorney Jeff Meyer told Judge Daniel Forgey that Barrett’s criminal history stretches back to 2002, and that any years since that he was not charged with a crime were ones in which “he was incarcerated.” Meyer noted that Barrett was on parole for a 2021 offense where he bit a hospital security officer’s finger nearly off when he was arrested on May 13, 2025, for methamphetamine possession and a parole violation. At the jail, Barrett bit a Natrona County Sheriff’s deputy’s finger as he was being secured in a restraint chair. On the way to the jail, he had been banging his head against the cage and told officers he was “crocodilian.” During his initial court appearance, Barrett stuck his tongue out and barked at the judge.

Meyer introduced photos of the deputy’s injury, saying, “This is not just a bite of the fingertip, it is a disfigurement of the fingertip.” He also noted that Barrett had bitten his own father, causing injuries. “He is a danger to the community,” Meyer said, asking for 30 to 35 years.

Defense attorney Jonathan Foreman said Barrett’s previous run-ins were mostly misdemeanors. After a crash that resulted in Barrett losing his left leg, he was diagnosed with bipolar disorder. Foreman argued that a blood test showed only a “therapeutic” level of meth, and Barrett likely had not taken his bipolar medication. He said Barrett does well on his “medication regime” and has been a model inmate for 368 days, asking for 10 to 20 years.

Barrett, who uses crutches after losing his leg, told the judge, “I know it doesn’t look good and the biting is repetitive. I can’t stop doing meth, it slows the voices down sometimes.” He asked for “a little bit of mercy.”

Forgey accepted the plea agreement and recommended that Barrett participate in an intensive treatment unit program within the Wyoming Department of Corrections.

The case began when a probation and parole check on May 13, 2025, found Barrett with a plastic bag of marijuana and a glass pipe used for meth. On the way to jail, Barrett said he was “crocodilian” and made growling noises. At the jail, he fought deputies and was placed in a restraint chair. A deputy controlling Barrett’s head from behind had his ring finger bitten “through the flesh and glove tearing away part of the finger from the first joint.” The deputy received stitches to keep his finger intact.
