Amber Alert Update: 12-Year-Old Boy Found Safe in Oceanside

A woman who allegedly abducted her 12-year-old son in Long Beach was arrested in Oceanside today about 90 minutes after a statewide Amber Alert was issued.

Sri Ann Johnston, 48, was arrested at about 2:40 p.m. by members of the U.S. Marshal's Fugitive Task Force, according to Nancy Pratt of the Long Beach Police Department. She allegedly abducted her son, Nicholas, on Thursday afternoon, authorities said.

Shortly after her arrest, the District Attorney's Office announced that it had charged Johnston with one count each of kidnapping and child custody deprivation. She is expected to be arraigned later this week, and faces up to 13 years and eight months in prison, prosecutors said.

According to prosecutors, Johnston picked Nicholas up last Wednesday for visitation, but failed to take him to school the next day.

The boy was recovered safe when Johnston was arrested today, Pratt said, adding that the boy's father has primary custody of the child.

Pratt said an Amber Alert was not issued until today because the case did not initially "meet the criteria" for the alert. She said an alert was declared once "new information" was gathered.

She said Sri Johnston was only allowed to have the child "in a very specific time frame. She was in violation of that."

The Amber Alert likely got the attention of many cell phone owners, thanks to a notification system that prompts a loud alert sound to emanate from mobile devices.
