Four days after Amber Dubois was last seen about a block from Escondido High School, searchers targeted their efforts in North Escondido.
Amber Dubois,14, was last seen just after 7 a.m. on Friday about a block from Escondido High school. The girl's parents said she was especially excited to get to school to exchange Valentine's Day gifts with friends.
Four days later, police investigators were on campus questioning Amber's classmates. On Tuesday night, 75 people with the sheriff's department and Escondido police went door-to-door searching for Amber after a student said she had seen Amber near Rincon Middle School on Sunday.
The student didn't know Amber was missing until she went to school Tuesday morning.
Search-and-rescue teams canvassed the neighborhood near the school, passing out fliers and speaking to residents.
Amber's father, Maurice Dubois, said he was encouraged to hear of the latest lead, but Escondido police Lt. Bob Benton said the search was over by 10:30 p.m. and did not yield any additional information about the teen's whereabouts.
On Saturday, police received a report of Amber seen walking near Palomar Medical Center with two other teens but have been unable to confirm that report, according to the North County Times. The teen's cell phone was activated for a few seconds Saturday afternoon, but other than that, her parents said, it has been off since she disappeared.
Escondido Union High School District released a statement to parents Tuesday suggesting they remind their own children to pay attention to their surroundings and walk in groups.
"We are concerned about Amber and are working in conjunction with the Escondido Police Department," the statement reads.
Anyone with information about Amber is asked to call Escondido police at 760-839-4722.
