Police said the mother was apparently dropping off the two boys at their father's house in the 10400 block of McBroom Street around 10:45 a.m. when the former couple got into an argument and Ortega allegedly shot the mother, said Smith. Ortega then fled with the children.
The woman, whose name was not immediately available, suffered multiple gunshot wounds and remains in serious condition, Smith said.
An Amber Alert for the boys, identified as 3-year-old Luis Gonzalo Ortega and 5-year-old Diego Fabian Ortega, was issued about two hours later due to lack of cooperation from the suspect's family, police said.
Diego is 5 years old and was last seen wearing a blue and green checkered shirt, blue jeans and white shoes. Luis is 3 years old. The toddler was last seen wearing a red checkered shirt and white shoes.
According to police, their father is described as a male, Hispanic, black hair, brown eyes, approximately 5 feet 6 inches tall, 180 pounds and has a medium build and a light complexion.
If contacted, Ortega is to be considered armed and dangerous.
Anyone with information regarding the whereabouts of Diego, Luis and Jose is asked to call 911. For any additional information, please contact Foothill Division Detectives at (818) 756-8861.
