A Casper man will be spending time behind bars after beating up his then girlfriend and acknowledging his prior criminal history.

Tamani Thompson was sentenced to 18-to-20 years in prison, after a jury found him guilty on three counts of aggravated assault and battery, and one count of domestic battery third offense.

On top of the aggravated assault and battery charges, Thompson was labeled as a habitual criminal.

Investigators with the Casper Police Department say in early May, officers responded to a residence on Breck Avenue and met up with the victim who had various bruises on her face and hands.

The victim said she had been asleep when she was abruptly awakened by Thompson who started attacking her, stating he had found something on her cell phone that suggested infidelity.

Officers eventually found Thompson shortly after they received another call, that he was trying to re-enter the residence where the attack took place.

They noticed he had freshly dried blood on his hands and on his t-shirt.

Thompson refused to answer any more questions regarding what had happened.

At his sentencing hearing, Thompson said he took the case to trial because he wanted the truth to come out, and it didn't, because the victim had several different recollections of events, however during the trial, prosecutors said the victim had a concussion.

Normally aggravated assault and battery is punishable by up to 10 years in prison, but because of the habitual criminal tag, he could have received anywhere from 10-to-50 years.

His actual sentence was 18-to-20 on each of the three counts of aggravated assault and battery (enhanced by habitual criminal), and three-to-five years for domestic battery.

All of those sentence will run concurrent with each other, or at the same time.

Thompson's prior criminal history includes convictions out of Cheyenne for felony drug possession and domestic battery.
