(SAN FRANCISCO) -- Police are searching San Francisco's Golden Gate Park for a teacher who mysteriously disappeared after leaving a cryptic message on her classroom blackboard.
English teacher Debra Schmitt, 53, scrawled "Thank you everyone" on her Tierra Lind High School classroom's chalkboard, but did not show up to class on Jan. 20 and has not been seen since.
Authorities found her classroom keys in the room. At her Ross, Calif., home police found her house keys, identification, purse and car parked outside.
Police said there were no indications that Schmitt had been abducted, but a cousin told ABC News that the teacher and mother of a 14-year-old boy had been upset and dealing with a number of personal issues. Linda Czarnik said Schmitt's husband filed this month for divorce and several close family members had died recently. One relative, a policeman, was killed by a drunk driver on Thanksgiving.
On Wednesday, police searched Phoenix Lake and Ross Creek outside San Francisco where she liked to hike, but did not find anything.
