Father Allegedly Slits Kids' Throats As Son, 8, Begs For Life: 'Daddy, I Am Sorry'

In his final moments, an 8-year-old boy pleaded for his life, uttering tragic last words — "Daddy, I am sorry" — before he and his baby sister were senselessly slain, according to police.

His father, 62-year-old Jean Pierre Ndossoka of Texas, allegedly slit the child's throat before turning his weapon on the boy's 1-year-old sister, Anna-Belle, according to court documents.

Ndossoka faces two counts of capital murder in the deaths.

The gruesome killings occurred after the children's mother, Ndossoka's estranged wife, dropped the pair at his apartment for a visitation, according to a Twitter briefing from Assistant Chief Wendy Baimbridge of the Houston Police Department.

Ndossoka killed both children on Saturday, authorities said. He told police that young daughter "just kept crying" as the killing occurred, KHOU 11 reported, citing court documents.

Ndossoka then called his wife, Sabine Ntongo, to tell her he had killed the children and left a "present" for her, according to Fox News.

When the mother arrived at the Houston apartment, she found both children dead on the bed, Baimbridge said.

The father had left the scene, but left behind a bloody knife and a note written in French that said he planned to kill himself as well, Fox News reported.

Ndossoka was later located by police at about 1 a.m. on Sunday in his vehicle in Pasadena, Texas. He had "unsuccessfully attempted to commit suicide by a firearm" and was taken to Clear Lake Regional Hospital where he was listed in stable condition, according to a statement from the Houston Police Department.

He later told investigators he "did something bad," according to Fox News.

Ndossoka is being held in the Harris County jail on two counts of capital murder, according to jail records. His court date is scheduled for August 15.
