Prosecutors charge former Prairie Park speech pathologist with sex crimes against 6 additional kids

Share this post or save for later

Douglas County prosecutors have filed 12 additional charges against a former Prairie Park Elementary School employee, now alleging that he sexually assaulted seven children.

Mark E. Gridley, 61, was initially charged with one count of aggravated indecent liberties with a child younger than 14 and one count of kidnapping, both alleged to have occurred on Feb. 7.

An updated charging document includes 14 total counts, repeating the same two charges for each of seven elementary-age children.

Gridley’s preliminary hearing, where the judge will determine whether there is enough evidence for the case to proceed to trial, has been delayed until Oct. 2, 3 and 6, from 9 a.m. to 5 p.m. each day.

An affidavit associated with the charges as they currently stand detailed the initial student’s police report, which was made on Feb. 8, the day after the alleged incident. However, police received a report involving a second child on Feb. 10, and the following day announced that they believed there could be more alleged victims, including students who did not receive speech services.

Prosecutors told the judge during a hearing in May that they intended to file additional charges.

After the initial report, Gridley, who had worked at Prairie Park since August 2021, was immediately relieved of all duties for the school district. His contract was formally terminated by the school board on Feb. 24.

Defendants in criminal cases should be presumed not guilty unless they are convicted. Gridley remains in custody of the Douglas County jail on a $1.5 million bond. 

A civil suit filed March 6 on behalf of one of the alleged victims states that Gridley “used his position of trust and authority to isolate, groom, and/or sexually abuse students under the guise of speech therapy, including Plaintiff.”

The suit asserts that the school district “knew, or had reason to know, Gridley engaged in acts of misconduct consistent with a dangerous propensity for unwanted or abusive contact with minor children and students, like Plaintiff.” It does not elaborate with further information about that allegation.
