DEATH row inmate David Renteria – before being executed – stared directly at the family of a five-year-old girl he snatched at Walmart and brutally killed.

The twisted monster prayed, sang and asked for forgiveness for slaughtering little Alexandra Flores before Christmas.

He had been convicted of strangling the girl taken from an El Paso store and then burning her body.

Renteria was already a convicted sex offender on probation when he was seen on a Walmart security video leaving the store with Flores.

The girl had wandered from her family doing Christmas shopping in November 2001. She was the youngest of eight children in her family.

Her remains were discovered the next day in an alley.

Blood found in Renteria’s van matched the DNA of the slain girl.

LETHAL JAB

Renteria, 53, was pronounced dead at 7.11pm CST following an injection at the state penitentiary in Huntsville, Texas, for the killing.

His victim’s relatives entered the death chamber and watched through a window, just a few feet from him.

Before being given a lethal injection, the killer told those gathered: “I’m sorry for all the wrongs I have done.

“And for those who have called for my death, who are about to murder me, I forgive you.”

Renteria also sang a hymn in Spanish, then prayed with a spiritual adviser standing next to him, and sang another hymn in English.

“FATEFUL”

He looked directly at the girl’s family, and told them: “There is not a day that goes by that I do not think about the fateful events of that day and what transpired.

“There are no words to describe what you’re going through, and I understand that.”

He told his sister and a friend, watching through another window: “I love you all, I truly do. I’ll see you in the next life.”

He was pronounced dead 11 minutes later after receiving a lethal dose of a powerful sedative.

TIME TO “HEAL”

After they had watched the monster die, Ignacio and Sandra Frausto held a photo collage of their slain sister while speaking with reporters.

A sobbing Ignacio said: “It took 22 years but the time came.

“It is done. We can finally and really begin to heal — 22 years of wondering what was going to happen.”

Renteria’s execution went ahead after the U.S. Supreme Court declined two separate defense requests for a stay earlier in the day.

Authorities said evidence showed Renteria, a convicted sex offender, carried out the abduction and killing alone.

He was the eighth inmate in Texas put to death this year.

There have been 23 executions in the U.S. so far this year, including two carried out on Thursday.
