Richard Concepcion, 37, was in critical condition all day after police said he fatally shot his estranged wife and then fled with their 18-month-old son.
The baby was found safe by police in the backseat of his father's pickup truck, but Concepcion was rushed to the hospital for a self-inflicted gunshot wound.
Police said they got a call to assist a custody exchange between Concepcion and the boy's mother this morning.
A few minutes later, dispatchers took a second call that shots had been fired at the home.
Police Chief William McManus said officers found the woman dead on the doorstep at her home.
