Shackled and handcuffed, Letecia Stauch did not speak during a court appearance in El Paso County Wednesday where she was formally charged with first-degree murder in the death of her stepson, 11-year-old Gannon Stauch, who has been missing since Jan. 27.

Letecia Stauch was the last person to see Gannon alive; his body has not been found.

Authorities have filed more than 107 search warrants in the case and expect to have at least 1,000 pages of discovery, Fourth Judicial Senior Deputy District Attorney Michael Allen said during the hearing, which was attended by Gannon’s parents and some supporters.

“With five weeks of strong, active investigation, it’s generated a lot of evidence,” Allen said.

Authorities have not publicly detailed the evidence that led investigators to Letecia Stauch, and a probable cause statement with that information has been sealed since it was filed on Feb. 28.

Judge Gregory Werner on Wednesday ordered the prosecution to immediately give the defense the probable cause statement, which the defense had not received because it was sealed.

A group of news organizations, including the Denver Post, have asked Werner to make that affidavit public. He did not rule on that motion during Wednesday’s hearing and is expected to address the issue later.

Allen said the prosecution does not object to making the affidavit public at this point, because he does not believe releasing the document will compromise the investigation.

“We feel like we’ve got the person responsible for the crime,” he said.

Gannon’s father, Albert Stauch, 37, filed for divorce last week. He and Letecia Stauch married in 2015, according to the filing, and moved to Colorado Springs in early 2019 when Albert Stauch received orders from the Colorado National Guard.

Letecia Stauch worked as a part-time substitute teacher for five months in early 2019 for Widefield School District and served as a full-time teacher at French Elementary School in Colorado Springs from August to December, according to the divorce filing.

She was offered a job at Mountain Ridge Middle School in Academy District 20 and attended three days of orientation from Jan. 22 to Jan. 24, district spokeswoman Allison Cortez said.

The school district rescinded her employment after discovering “strange inconsistencies” in her job application and paperwork, Cortez said. Letecia Stauch failed to disclose that she’d previously lost her teaching license in another state and left out some of her past employment information, Cortez said.

School officials were not able to contact Letecia Stauch by phone in the next couple of days; she was eventually notified of the decision in a letter that was mailed Jan. 30.

Cortez was not sure if Letecia Stauch learned about her job loss some other way before Gannon Stauch went missing on Jan. 27.

“She did not show up for work after Friday,” she said. “But unfortunately because of the investigation I can’t share further details about what was communicated to us from her.”

Letecia Stauch’s teaching license was suspended in South Carolina for six months in 2016 after authorities there found that she’d breached a contract in which she’d agreed to serve as a social studies teacher at a middle school. Letecia Stauch attended a five-day orientation and the first two days of school, but then abruptly stopped showing up, according to documents filed by the state’s board of education, which determined the breach of contract warranted a suspension.

Letecia Stauch also previously worked as a special education teacher for Horry County Schools in South Carolina. She started as a paraprofessional in 2010 and became a teacher in 2012. She resigned in 2015.

In April 2016, she sued the school district, alleging that an assistant principal subjected her to “inappropriate sexual advances, comments and gestures,” according to the federal lawsuit. The school district and assistant principal denied the allegations, and the lawsuit was settled outside of court in 2017, court records show.

Letecia Stauch previously pleaded guilty to simple assault in North Carolina in 2004, when she was 20.
