ST. JOHNS COUNTY, Fla. -

After a three day trial, a St. Johns County jury deliberated for about 30 minutes Thursday before finding 38-year-old David Martinez guilty of sexual battery on a minor.

According to the affidavit, between 2005 and 2010, Martinez repeatedly raped the victim, beginning when she was 7 years old.

The victim testified that Martinez blindfolded her or put a blanket over her head when he sexually abused her. The victim said Martinez would conduct an “upper and lower test” on her.

“There are few crimes more disgusting than abusing the trust of a child to engage in sexual crimes," State Attorney R.J. Larizza said. "The courageous testimony of the victim made justice a reality in this case.”

Assistant State Attorneys Jennifer Dunton and Kelly Wark prosecuted Martinez.

“In her own journal and in her own words, the victim wrote, 'It feels like I am being raped,' and, 'I am scared out of my mind,'" Wark said.

“The victim deserves the last word, and the last word is guilty; the defendant is guilty of sexually abusing a 7-year-old girl until she was 12," Dunton said.

Martinez is charged with two counts of sexual battery on a person younger than 12, a capital felony; and three counts of sex battery; and engaging sex conduct on a minor 12 to 18 years of age, a first-degree felony. 

Following the verdict, the judge sentenced Martinez to two life terms for counts one and two; and 30 years in prison for counts three, four and five, to run consecutive, a total of 90 years in prison to the two life terms.
