A registered sex offender was sentenced to life in prison for raping and infecting a 14-year-old girl and a 23-month-old toddler with HIV, chlamydia and herpes.

David Wilson, 34, of Houston, Texas, was found guilty of the teen girl's rape on Thursday.

Wilson claims he was 'in love' with the girl and still is.

The child told investigators she knew Wilson through a family member and they had sex multiple times.

She tested positive for HIV and herpes and she was pregnant with Wilson's baby.

In a court affidavit, she said that she and Wilson 'would park on a cul-de-sac near her school and have sex in his car. The last time, they had unprotected sex'.

Wilson was unapologetic about their relationship.

'I have never denied about us having a relationship.

'I am not sorry we were together, no, I am sorry the HIV came into the situation,' Wilson said in court.

During the trial, investigators brought up the other victim, a 23-month-old baby, who was living at Wilson's residence at the time.

It was discovered the infant was assaulted after doctors found a growth on her genitals and tested her for the STDs.

Doctors concluded the only way the toddler could have become infected was through sexual assault.

The four adults in the household were tested for the diseases - Wilson was the only one to come up positive for all three.

Wilson said he was 'in love' with the 14-year-old and still is. The girl said she was pregnant with his baby and that they had sex multiple times

Doctors performed reconstructive surgery on the toddler because of damage from infection.

Wilson said he also had intimate relations with several unidentified women, who may also be at risk.

He also had access to other juveniles.

Wilson was employed by fast food establishments in the Houston area

He was sent to prison for sexually assaulting another teenager in Harris County, Texas, in 2005 and was released in 2009.
