DECATUR, Ga. (AP) - A Georgia man who shot and killed a toddler's father outside a suburban Atlanta preschool has been found guilty but mentally ill.

The jury's decision Thursday means Hemy Neuman will go to prison but he will get mental health treatment while serving his sentence for the killing of Russell Sneiderman in November 2010. He could face up to life in prison.

Neuman's attorneys argued he could not tell the difference between right and wrong when he shot and killed Sneiderman. Prosecutors had charged him with murder, saying the killing was by a jealous man who wanted Sneiderman's life.

Sneiderman's wife Andrea worked with Neuman at General Electric, and defense lawyers and prosecutors linked the shooting to an affair between the two. She has denied those allegations.
