PITTSBURGH (AP/PIX11) — Police say a Pittsburgh elementary school teacher who resigned this month was obsessed with one of her 11-year-old students, encrypting her phone number on the girl’s math homework, exchanging thousands of text messages with her and even talking of running away with her.

Twenty-eight-year-old Geraldine Alcorn was arraigned Wednesday on charges of child luring, corruption of minors and attempting to interfere with custody of the child. She was jailed after being unable to post $100,000 bond.

The student’s mother told WPXI that 2,400 text messages were exchanged between her child and the Beechwood Elementary School teacher over a two-week span.

Alcorn allegedly hid her phone number on a math worksheet by telling the girl to dial numbers that had been circled, police said.

The texts reportedly expressed “deep love” between Alcorn and the student. The pair talked about Alcorn adopting the 11-year-old, texting that they would be “on the run” for a while.

Police said after the girl’s mother discovered the messages on her iPod, she found handwritten letters in her daughter’s school binder labeled “Things Ms. Alcorn and I can do,” “What we can do” and “When we can do it.”

Police don’t believe Alcorn’s attraction to the girl was sexual but said she continued to leave gifts and letters for the girl at school even after the girl’s mother complained and Alcorn resigned on March 2.

Pittsburgh Public Schools officials said staff “were made aware of concerns that a teacher had developed an improper attachment” with the student and was suspended.
