Girl, 8, missing from San Dimas home is found in Oklahoma

She told authorities she was waiting for another foster child she had run away with, Estephanie Flores, 12, and for Flores' biological mother, Iris Pineda Zavala, 38, of Monrovia and an unidentified man traveling with them.

The girl told police that Zavala said she and the others were going to go do something and never returned, said Los Angeles County Sheriff's Lt. Michael J. Rodriguez.

The three are believed to still be in the Miami area of northeastern Oklahoma, near the Missouri border. Estephanie Flores is 4 feet, 11 inches tall and weighs 130 pounds, and was wearing a blue sweater and blue jeans.

Robin was tired when found and had not been interviewed at length this afternoon, Rodriguez said.

"She was disheveled, very hot. It's 95 degrees there," he said.

Sheriff's investigators alerted Miami police to be on the lookout for the girls at 9:30 a.m. after uncovering evidence that they had fled east on Interstate 40 with Zavala and the unidentified man, Rodriguez said.

They believe Estephanie befriended Robin, then used the younger girl's cellphone to plot to run away with her mother. Estephanie then allegedly drove her foster parents' car away from home early Monday as they slept, traveling with Robin to meet Zavala and the unknown man. (Authorities earlier today incorrectly said the girls had disappeared Sunday.)

The adults then drove the two girls to Oklahoma, Rodriguez said.

"This was a pre-planned event," Rodriguez said.

Estephanie had been in the foster home for five months, Robin for a month, Rodriguez said.

Authorities are now seeking Zavala in connection with allegations of kidnapping, child abduction, child abandonment and grand theft auto, Rodriguez said.

He said it was not clear how soon Robin will be returned to California.

Anyone with information about the case is asked to contact investigators at (909) 450-2711.
