WATCH Why the first 72 hours in a missing persons investigation are the most critical

An 11-year-old girl vanished in Northern California after leaving for school and local police officers believe she may be a runaway.

Elianah Nhem was last seen at her apartment in Stockton at 6:30 a.m. Tuesday, Stockton Police Department officials said.

Elianah's mother believes she left to walk to school but she never showed up, according to police.

Elianah Nhem, 11, has gone missing in Stockton, Calif., according to police who released this image seeking help finding her.

Authorities believe this may be a runaway case though it's not clear why the 11-year-old might have left home, Stockton Police spokesman Joe Silva told ABC News on Wednesday.

Officials do not know where Elianah is but are mostly focusing the search within her neighborhood and near her school, Silva said.

Stockton is located about 80 miles east of San Francisco.

The "goal here is to locate her and make sure she's safe -- and were asking for the community's help," Silva said. "Do the right thing and give us a call because she has family members who are very worried."
