Another hot car death has a Houston family in mourning.

A 36-year-old father of three dropped off two of his three children at daycare. But he failed to leave his seven-month-old son with the family babysitter.

Instead, the baby was left behind inside his father’s hot car and died.

Investigators questioned the father and released him, pending further investigation.

This is the sixth hot car death in Texas in 2017.
