Texas man is found with a self-inflicted gunshot wound after he stabbed his children

A Texas man who confessed to fatally stabbing his two children has been hospitalized after police found him with a self-inflicted gunshot wound in his car.

Houston police say 61-year-old Jean Pierre Ndossoka was taken to a hospital in stable condition Sunday after authorities located him in Pasadena, just southeast of Houston.

Police say he's expected to survive, and court records indicate he's charged with capital murder.

Ndossoka's recently-estranged wife Sabine Ntongo had dropped their one-year-old daughter and eight-year-old son off at their father's apartment for visitation on Saturday.

Police say at around 3.30pm Ndossoka called her and told her he'd killed the children.

Ntongo called 911 and rushed over to Ndossoka's apartment in southwest Houston, where she found both children stabbed to death, lying on the bed.

Ntongo was in tears outside of the Houston home after finding her children stabbed to death.

Heartbreaking photos show the mother being comforted by family members.

The Houston Chronicle reports that she had been married to Ndossoka for six years before they separated recently.

Police put out a vehicle description and mounted a search for the 61-year-old who had fled the home.

It was not immediately clear how authorities located him.

Ndossoka is due to appear in court on Monday morning on capital murder charges.

If convicted he could face the death penalty.
