Respectful, charming and smart, 22-year-old Lekurt Fisher should've been valedictorian of his graduating class at Brownwood High School.

But there was another side to Fisher: lawlessness.

That was the conflicting description witnesses gave of Lekurt in a punishment hearing Friday in 35th District Court. Fisher was found to have violated the probation he was serving for sexual assault of a child.

District Judge Steve Ellis sentenced Fisher to 18 years in prison, who began cursing loudly as courthouse deputies led him out of the courtroom. Once out of the courtroom, Fisher head-butted a wall near the entrance, leaving a softball-sized indentation.

Courthouse deputies quickly subdued Fisher and took him outside to a patrol car, where he was driven to the Brown County Jail.

Probation officer Jay Curtis, who witnessed the incident, said it was both surprising and scary but said deputies did a good job handling Fisher's outburst.

"It was crazy," Curtis said. "We saw that Jekyll and Hyde."

The outburst happened as prosecutor Christina Nelson handled her first contested hearing since joining the district attorney's office in August.

Fisher had been placed on deferred adjudication probation for having sex with a 14-year-old girl, court records show. Fisher was 19 at the time and the girl's father had given Fisher permission to have sex with the girl, according to earlier testimony. The girl's father was sentenced to prison.

Ellis found that Fisher had violated his probation in numerous aways including committing new offenses including aggravated assault with a deadly weapon, making a terroristic threat and receiving and concealing stolen goods, Curtis said.

Ellis was respectful and encouraging toward Fisher, encouraging him to complete his sentence, pursue an education and be productive, Curtis said.
