A 35th District Court jury denied Robert Worthy’s request for probation for having sex with a 15-year-old girl, sentencing him instead to eight years in prison.

Worthy, 41, pleaded guilty Monday to two counts of sexual assault of a child, and chose to be sentenced by a jury.

The panel heard testimony Tuesday and Wednesday of Worthy’s months-long sexual relationship with the girl, which began in December 2003, according to testimony.

The charge, a second degree felony, carries a maximum sentence of 20 years in prison. Assistant District Attorney Sam Moss had asked jurors to assess a “mid-range” sentence of 10 to 15 years.

“I’m begging the jury,” Worthy said when his attorney, Fred Franklin, asked him if he wanted jurors to place him on probation.

Worthy, a surgical technician, previously lived in Brownwood and lived in Waco at the time of his trial.

The victim, now 19, went to live with Worthy, his then-wife and their two children because her mother had died and her father was in prison, according to testimony.
