A court appearance set for Tuesday for former Westlake High School teacher Haeli Noelle Wey has been rescheduled for December.

Wey is charged with two counts of improper relationship between educator and student. Both counts are 2nd degree felonies.

She was a math teacher at Westlake High School until October 30, 2015.

According to court documents, Wey and one of the the victims had been communicating with each other through social media since the start of the school year in 2015. The alleged incident that led to the current charges happened during a hike in September. The arrest affidavit listed a series of texts between Wey and the victim that shows her inviting the victim on the hike and then asking the victim to delete the conversation from their phone.

Court documents say a juvenile witness found the exchange on the victim's phone and alerted authorities. The victim then provided details of the improper encounter to investigators during an interview.

The incident with the second student occurred during the summer. According to the affidavit, Wey invited the victim to her home where they had intercourse. The sexual relationship allegedly lasted several months. Authorities became aware of the incident after the victim made an outcry to their parent, who then alerted law enforcement.
