HOUSTON – The Chapa family's photo album is filled with memories, but not all of them are pleasant. That's because the album includes photographs from the day 17-year-old Joshua Chapa was stabbed at Wunsche High School.

“When I was laying on the ground, it felt cold. It was lonely, and I thought it was my last day on Earth,” said Joshua Chapa.

Fortunately, the high school senior was able to use his cell phone.

“I was trying not to cry. I told my mom that I just got stabbed,” said Chapa. 

Chapa was attacked by Ruben Cuellar, the father of a classmate.

According to Cuellar, his 17-year-old daughter claimed she had been raped at a wild party.  So he took the law into his own hands and attacked Chapa. Cuellar is currently serving six years in jail for his crime.

“My daughter told me he was one of them,” said Cuellar. “I went ballistic with rage. I didn't know the person I had become.”

His daughter has since admitted that she had lied about being raped. She even pled guilty to filing a false police report.

Despite her lies and the rage he felt, Cuellar said his daughter is his princess. In fact, Cuellar, who has previous misdemeanor convictions, still believes something happened to his daughter that night.

“I'm going say it’s half and half,” said Cuellar.

When asked if his daughter possibly made up the lie out of fear of being punished, Cuellar laughed. He said the worst punishment he’s ever enforced was taking away his daughter's computer and game time.

Cuellar believes that his sentence should be reduced because of his mental state. But his victim, who suffered because of his daughter’s lie, doesn’t agree.

“I feel like it is an embarrassment to the justice system that he just got six years, and he could get out in three,” said Chapa.

Chapa and his father are equally upset at the girl’s punishment for the lie that triggered the attack.

“Receiving only probation for something that changed three lives and two families is not enough,” said Robert Chapa, Joshua's father.

Cuellar said his daughter visits him twice a week. 

Meanwhile, Chapa is hoping for a new state law that mandates 10 years for any adult convicted of attacking a child on a school campus.
