A San Antonio man, convicted of molesting two young girls knowing he had HIV, was handed three sentences of life without parole Thursday along with two 20-year terms.

It took jurors about five hours to determine the punishment for Adam Salvador Delgado, 32, an Army veteran who contracted HIV while serving in Iraq in 2006. The molestations, of girls ages 7 and 11, was alleged to have occurred two years later.

Immediately after the verdict, state District Judge Philip Kazen opted to stack the sentences.

Delgado was charged with two counts of indecency with a child, second-degree felonies punishable by up to 20 years in prison, along with one count of continuous sexual abuse of a child and two counts of super-aggravated sexual assault of a child.

To be found guilty of super-aggravated sexual assault, which carries a punishment range of 25 years in prison to life, jurors had to agree that Delgado used his bodily fluids as a deadly weapon while molesting a child younger than 14.

It was the first time the offense, a relatively new addition to Texas law, was tried in San Antonio. It also appears to be the first time that HIV has been deemed a deadly weapon at a trial in Bexar County, prosecutors have said.

Delgado, who moved to San Antonio with his wife after serving at Fort Hood, was arrested in November 2008. Jurors returned guilty verdicts Wednesday.

During closing arguments for the punishment phase, prosecutors Catherine Hayes and David Martin asked jurors for the maximum sentences on all five charges.

"Anything less than life is the definition of injustice," Hayes said, explaining that it would be the only way to give Delgado's victims peace of mind.

Defense attorneys Michael Reyes and Roy Barrera pointed out that Delgado would be 57 when released from prison if given the minimum sentence of 25 years. That seemed like punishment enough, they suggested, reminding jurors of his military service.
