A former staff member of a Christian private school in Tuolumne accused of sexually abusing female students in the 1990s did not enter a plea on Friday in the Tuolumne County Superior Court, but instead plans to challenge the charges against her during a hearing set for Aug. 23.

Clint Parish, the Sonora defense attorney representing Mona McGrady, 61, a former coach and physical education teacher at the private Mother Lode Christian School, said he planned to file a demurrer.

Parish said the demurrer was a challenge to charges, indicating there was “no legal basis to the charges as written.”

“There will be a lot in the demurrer,” Parish said following the brief hearing.

Parish declined to discuss the specific claims that would be made. He said he planned to file it with the Tuolumne County Superior Court in late July.

McGrady was charged in May on suspicion of 13 counts of lewd and lascivious acts with a child 14 or 15 years old and one count of sexual penetration with a foreign object of a person under 18 years of age, which law enforcement alleged occurred against female students while she was employed with the school.

The hearing on Friday in Department 2 of the Tuolumne County Superior Court focused primarily on the scheduling of the demurrer hearing.

Judge James A. Boscoe asked Parish if McGrady had entered a plea, but Parish responded his intention was to seek to demurrer first.

At McGrady’s previous hearing on May 31, Parish said he was awaiting discovery documents from the District Attorney’s Office, but added she denied the charges detailed in a seven-page affidavit filed with the court on May 16.

The affidavit described 14 incidents in Tuolumne and Stanislaus counties between Jan. 24, 1994 to Jan. 24, 1997.

The earliest allegation described in the affidavit was at a cabin in Pinecrest when the victim was 14, and allegedly became more frequent as the victim grew older.

Five incidents were alleged to have occurred when the victim was 15 years old at a Mother Lode Christian School office during the school’s volleyball season. Six other incidents are alleged from when the victim was 15 — twice at McGrady’s house, twice at the “Acquire the Fire” youth religious conference in Modesto, once in a school office during basketball season and once at the victim’s house.

Another incident allegedly occurred at a motel in Modesto during a tournament at Modesto Christian School when the victim was 17.

According to the complaint, the victim reported to law enforcement on Dec. 3, 2018 and a more than six month investigation followed.

Current California law dictates that charges must be filed within one year of a report being made to supercede the statute of limitations.
