HOUSTON -- Marcos Garza knows a lot of people would lock him up and throw away the key; but, he’s still asking for forgiveness.
When Garza was 19 years old, he killed a Catholic nun while he was driving drunk in south Houston.
Garza is now 21 years old.
He pleaded guilty to intoxication manslaughter and was sentenced to eight years in prison.
The South Houston High School graduate killed Sister Therese Huang Do when he smashed his truck into her car two years ago.
It happened on a Sunday morning just before sunrise. Garza was coming home from a party.
Sister Huang Do was on her way to do church work when Garza’s truck slammed into her car on Minnesota Street.
“I would take her place any day,” Garza told KHOU 11 News.
Tucker Graves says his client deserves a second chance.
“I would ask those who are so quick to condemn, look inside your heart what if it was your son or daughter that was involved in this and it was a one-time incident,” said Graves.
Garza says all he wants is to be forgiven by Huang Do’s family.
“There's probably people that don't believe me, but I know God believes me,” Garza said from inside the jail. “I know he's going to help me through this.”
Garza’s drinking had gotten him in trouble before that fatal wreck. He was arrested for public intoxication a year earlier.
Ultimately, it took shackles and cuffs to turn his life around. Now he’s hoping to stop other teens from ruining their lives.
“I want to tell everybody out there to stop their drinking and driving don't do it because you hurt other people's families,” he said.
With prison now in Garza’s future, he admits that he’s scared.
During our interview, he became most emotional, when we asked about his mother.
Fighting back tears, he said, “Because I can't hug my mom… I can't leave whenever she leaves.”
Garza has also shed tears for Sister Therese.
He even went to her grave before he was locked up.
“I got down on my knees and I asked her mainly for forgiveness and I asked her to send a message to her family so they could forgive me as well,” he said.
