On September 18, 2017, 27-year-old Charles Pargo was fatally shot inside his Youngstown, Ohio home during a domestic dispute over custody of his three-week-old son. Pargo’s girlfriend had left the house with her other children, leaving Pargo holding the infant. The girlfriend’s parents, Louis Littlejohn and his wife, came to retrieve the baby. Pargo died at the scene.

Sixty-one-year-old Louis Littlejohn was arrested and charged with aggravated murder and was held on a $1 million bond. Investigators reported a prior altercation in November 2016 in which Littlejohn said Pargo had threatened him and often carried a gun. What details about the dispute or its escalation can anyone with knowledge of the parties add to the record?
