Two women were arrested Tuesday in the fatal shooting of a man in California, and a 4-year-old boy with them was found unharmed, police said.

Vanessa Ochoa, 22, and Mesha Arshaz Dean, 25, were taken into custody without incident, Las Vegas police Lt. Ted Lee said. The women had been sought for two days as authorities broadcast Amber Alert bulletins across California and Nevada.

The women were unarmed when they were found in a car driven by an unidentified man in a West Las Vegas neighborhood, Lee said. Ochoa's son, Manaen Miles, was turned over to Clark County child protective services officials.

"He was fine as far as we could tell," Lee said. "He didn't need any medical attention."

Lee said Ochoa and Dean were detained for questioning in the Sunday slaying of Monroe Miles, 32, the boy's paternal uncle, and for the abduction of her son from Miles' home in Altadena, a foothill suburb northeast of Los Angeles.

The Los Angeles County Sheriff's Department issued an Amber Alert on Sunday, saying Ochoa did not have legal custody of her son.

A sheriff's office statement alleged that Ochoa "shot and killed a relative who was caring for the child, took the child and left." Another statement said only that Dean "has been identified as having been involved in the commission of this crime."
